Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574250, here are decompositions:

17 + 31574233 = 31574250
47 + 31574203 = 31574250
151 + 31574099 = 31574250
157 + 31574093 = 31574250
179 + 31574071 = 31574250
229 + 31574021 = 31574250
251 + 31573999 = 31574250
283 + 31573967 = 31574250

Showing the first eight; more decompositions exist.
