Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514836, here are decompositions:

47 + 31514789 = 31514836
53 + 31514783 = 31514836
149 + 31514687 = 31514836
173 + 31514663 = 31514836
257 + 31514579 = 31514836
263 + 31514573 = 31514836
359 + 31514477 = 31514836
569 + 31514267 = 31514836

Showing the first eight; more decompositions exist.
