Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522656, here are decompositions:

23 + 31522633 = 31522656
43 + 31522613 = 31522656
59 + 31522597 = 31522656
73 + 31522583 = 31522656
103 + 31522553 = 31522656
107 + 31522549 = 31522656
127 + 31522529 = 31522656
163 + 31522493 = 31522656

Showing the first eight; more decompositions exist.
