Smile Mod functions related to Fermat's Last Theorem

Since Fermat's Last Theorem has been proved, can it be concluded that there can't be three different, relatively prime, non zero integers A>B>C where the following six Mod functions are all equal to zero when the power is odd and higher than one and all but the first Mod function are equal to zero when the power is even and greater than two?

1. A^n Mod (B + C)
2. B^n Mod (A - C)
3. C^n Mod (A - B)
4. (B^n + C^n) Mod A
5. (A^n - B^n) Mod B
6. (A^n - C^n) Mod C

Answer believe it or not is NO. There are such sets of three integers.
Before I reveal what they are, see if you can find them.
