Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574950, here are decompositions:

23 + 31574927 = 31574950
59 + 31574891 = 31574950
89 + 31574861 = 31574950
101 + 31574849 = 31574950
137 + 31574813 = 31574950
227 + 31574723 = 31574950
257 + 31574693 = 31574950
263 + 31574687 = 31574950

Showing the first eight; more decompositions exist.
