Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556514, here are decompositions:

13 + 31556501 = 31556514
37 + 31556477 = 31556514
47 + 31556467 = 31556514
53 + 31556461 = 31556514
97 + 31556417 = 31556514
107 + 31556407 = 31556514
173 + 31556341 = 31556514
191 + 31556323 = 31556514

Showing the first eight; more decompositions exist.
