Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499962, here are decompositions:

23 + 31499939 = 31499962
29 + 31499933 = 31499962
41 + 31499921 = 31499962
251 + 31499711 = 31499962
401 + 31499561 = 31499962
503 + 31499459 = 31499962
563 + 31499399 = 31499962
653 + 31499309 = 31499962

Showing the first eight; more decompositions exist.
