Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556528, here are decompositions:

61 + 31556467 = 31556528
67 + 31556461 = 31556528
139 + 31556389 = 31556528
379 + 31556149 = 31556528
547 + 31555981 = 31556528
571 + 31555957 = 31556528
607 + 31555921 = 31556528
811 + 31555717 = 31556528

Showing the first eight; more decompositions exist.
