Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574944, here are decompositions:

17 + 31574927 = 31574944
53 + 31574891 = 31574944
83 + 31574861 = 31574944
131 + 31574813 = 31574944
197 + 31574747 = 31574944
251 + 31574693 = 31574944
257 + 31574687 = 31574944
263 + 31574681 = 31574944

Showing the first eight; more decompositions exist.
