Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574746, here are decompositions:

23 + 31574723 = 31574746
53 + 31574693 = 31574746
59 + 31574687 = 31574746
89 + 31574657 = 31574746
107 + 31574639 = 31574746
239 + 31574507 = 31574746
257 + 31574489 = 31574746
293 + 31574453 = 31574746

Showing the first eight; more decompositions exist.
