Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476556, here are decompositions:

5 + 31476551 = 31476556
47 + 31476509 = 31476556
107 + 31476449 = 31476556
173 + 31476383 = 31476556
239 + 31476317 = 31476556
317 + 31476239 = 31476556
443 + 31476113 = 31476556
593 + 31475963 = 31476556

Showing the first eight; more decompositions exist.
