Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624634, here are decompositions:

3 + 31624631 = 31624634
7 + 31624627 = 31624634
37 + 31624597 = 31624634
43 + 31624591 = 31624634
127 + 31624507 = 31624634
157 + 31624477 = 31624634
211 + 31624423 = 31624634
271 + 31624363 = 31624634

Showing the first eight; more decompositions exist.
