Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556852, here are decompositions:

73 + 31556779 = 31556852
199 + 31556653 = 31556852
373 + 31556479 = 31556852
463 + 31556389 = 31556852
499 + 31556353 = 31556852
709 + 31556143 = 31556852
739 + 31556113 = 31556852
853 + 31555999 = 31556852

Showing the first eight; more decompositions exist.
