Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556596, here are decompositions:

59 + 31556537 = 31556596
107 + 31556489 = 31556596
173 + 31556423 = 31556596
179 + 31556417 = 31556596
293 + 31556303 = 31556596
317 + 31556279 = 31556596
347 + 31556249 = 31556596
353 + 31556243 = 31556596

Showing the first eight; more decompositions exist.
