Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463086, here are decompositions:

3 + 31463083 = 31463086
23 + 31463063 = 31463086
107 + 31462979 = 31463086
197 + 31462889 = 31463086
293 + 31462793 = 31463086
503 + 31462583 = 31463086
509 + 31462577 = 31463086
647 + 31462439 = 31463086

Showing the first eight; more decompositions exist.
