Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574064, here are decompositions:

17 + 31574047 = 31574064
23 + 31574041 = 31574064
43 + 31574021 = 31574064
97 + 31573967 = 31574064
103 + 31573961 = 31574064
107 + 31573957 = 31574064
211 + 31573853 = 31574064
233 + 31573831 = 31574064

Showing the first eight; more decompositions exist.
