Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556496, here are decompositions:

7 + 31556489 = 31556496
17 + 31556479 = 31556496
19 + 31556477 = 31556496
29 + 31556467 = 31556496
73 + 31556423 = 31556496
79 + 31556417 = 31556496
89 + 31556407 = 31556496
107 + 31556389 = 31556496

Showing the first eight; more decompositions exist.
