Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510014, here are decompositions:

5 + 31510009 = 31510014
7 + 31510007 = 31510014
13 + 31510001 = 31510014
23 + 31509991 = 31510014
43 + 31509971 = 31510014
47 + 31509967 = 31510014
73 + 31509941 = 31510014
101 + 31509913 = 31510014

Showing the first eight; more decompositions exist.
