Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510344, here are decompositions:

23 + 31510321 = 31510344
101 + 31510243 = 31510344
127 + 31510217 = 31510344
157 + 31510187 = 31510344
211 + 31510133 = 31510344
223 + 31510121 = 31510344
233 + 31510111 = 31510344
251 + 31510093 = 31510344

Showing the first eight; more decompositions exist.
