Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6654, here are decompositions:

17 + 6637 = 6654
47 + 6607 = 6654
73 + 6581 = 6654
83 + 6571 = 6654
101 + 6553 = 6654
103 + 6551 = 6654
107 + 6547 = 6654
163 + 6491 = 6654

Showing the first eight; more decompositions exist.
