Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556734, here are decompositions:

47 + 31556687 = 31556734
197 + 31556537 = 31556734
233 + 31556501 = 31556734
257 + 31556477 = 31556734
311 + 31556423 = 31556734
317 + 31556417 = 31556734
353 + 31556381 = 31556734
431 + 31556303 = 31556734

Showing the first eight; more decompositions exist.
