Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31558064, here are decompositions:

7 + 31558057 = 31558064
67 + 31557997 = 31558064
103 + 31557961 = 31558064
127 + 31557937 = 31558064
277 + 31557787 = 31558064
331 + 31557733 = 31558064
367 + 31557697 = 31558064
463 + 31557601 = 31558064

Showing the first eight; more decompositions exist.
