Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582064, here are decompositions:

37 + 31582027 = 31582064
43 + 31582021 = 31582064
61 + 31582003 = 31582064
67 + 31581997 = 31582064
103 + 31581961 = 31582064
181 + 31581883 = 31582064
271 + 31581793 = 31582064
277 + 31581787 = 31582064

Showing the first eight; more decompositions exist.
