Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516396, here are decompositions:

17 + 31516379 = 31516396
239 + 31516157 = 31516396
257 + 31516139 = 31516396
293 + 31516103 = 31516396
389 + 31516007 = 31516396
503 + 31515893 = 31516396
677 + 31515719 = 31516396
719 + 31515677 = 31516396

Showing the first eight; more decompositions exist.
