Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31487334, here are decompositions:

5 + 31487329 = 31487334
17 + 31487317 = 31487334
23 + 31487311 = 31487334
71 + 31487263 = 31487334
83 + 31487251 = 31487334
101 + 31487233 = 31487334
103 + 31487231 = 31487334
163 + 31487171 = 31487334

Showing the first eight; more decompositions exist.
