Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559086, here are decompositions:

5 + 31559081 = 31559086
17 + 31559069 = 31559086
59 + 31559027 = 31559086
89 + 31558997 = 31559086
113 + 31558973 = 31559086
227 + 31558859 = 31559086
239 + 31558847 = 31559086
263 + 31558823 = 31559086

Showing the first eight; more decompositions exist.
