Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556526, here are decompositions:

37 + 31556489 = 31556526
47 + 31556479 = 31556526
59 + 31556467 = 31556526
103 + 31556423 = 31556526
109 + 31556417 = 31556526
137 + 31556389 = 31556526
173 + 31556353 = 31556526
223 + 31556303 = 31556526

Showing the first eight; more decompositions exist.
