Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556606, here are decompositions:

127 + 31556479 = 31556606
139 + 31556467 = 31556606
199 + 31556407 = 31556606
283 + 31556323 = 31556606
313 + 31556293 = 31556606
457 + 31556149 = 31556606
463 + 31556143 = 31556606
607 + 31555999 = 31556606

Showing the first eight; more decompositions exist.
