Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450244, here are decompositions:

37 + 31450207 = 31450244
103 + 31450141 = 31450244
127 + 31450117 = 31450244
151 + 31450093 = 31450244
211 + 31450033 = 31450244
223 + 31450021 = 31450244
277 + 31449967 = 31450244
307 + 31449937 = 31450244

Showing the first eight; more decompositions exist.
