Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624716, here are decompositions:

17 + 31624699 = 31624716
43 + 31624673 = 31624716
73 + 31624643 = 31624716
89 + 31624627 = 31624716
103 + 31624613 = 31624716
157 + 31624559 = 31624716
239 + 31624477 = 31624716
293 + 31624423 = 31624716

Showing the first eight; more decompositions exist.
