Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556696, here are decompositions:

43 + 31556653 = 31556696
139 + 31556557 = 31556696
229 + 31556467 = 31556696
307 + 31556389 = 31556696
373 + 31556323 = 31556696
547 + 31556149 = 31556696
727 + 31555969 = 31556696
739 + 31555957 = 31556696

Showing the first eight; more decompositions exist.
