Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627816, here are decompositions:

5 + 31627811 = 31627816
23 + 31627793 = 31627816
53 + 31627763 = 31627816
89 + 31627727 = 31627816
167 + 31627649 = 31627816
239 + 31627577 = 31627816
257 + 31627559 = 31627816
443 + 31627373 = 31627816

Showing the first eight; more decompositions exist.
