Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556324, here are decompositions:

31 + 31556293 = 31556324
181 + 31556143 = 31556324
211 + 31556113 = 31556324
313 + 31556011 = 31556324
367 + 31555957 = 31556324
433 + 31555891 = 31556324
607 + 31555717 = 31556324
661 + 31555663 = 31556324

Showing the first eight; more decompositions exist.
