Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607426, here are decompositions:

3 + 31607423 = 31607426
127 + 31607299 = 31607426
163 + 31607263 = 31607426
199 + 31607227 = 31607426
379 + 31607047 = 31607426
463 + 31606963 = 31607426
523 + 31606903 = 31607426
547 + 31606879 = 31607426

Showing the first eight; more decompositions exist.
