Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613164, here are decompositions:

47 + 31613117 = 31613164
137 + 31613027 = 31613164
173 + 31612991 = 31613164
251 + 31612913 = 31613164
311 + 31612853 = 31613164
431 + 31612733 = 31613164
503 + 31612661 = 31613164
617 + 31612547 = 31613164

Showing the first eight; more decompositions exist.
