Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517044, here are decompositions:

5 + 31517039 = 31517044
17 + 31517027 = 31517044
23 + 31517021 = 31517044
71 + 31516973 = 31517044
233 + 31516811 = 31517044
257 + 31516787 = 31517044
263 + 31516781 = 31517044
347 + 31516697 = 31517044

Showing the first eight; more decompositions exist.
