Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624754, here are decompositions:

13 + 31624741 = 31624754
37 + 31624717 = 31624754
127 + 31624627 = 31624754
157 + 31624597 = 31624754
163 + 31624591 = 31624754
277 + 31624477 = 31624754
331 + 31624423 = 31624754
367 + 31624387 = 31624754

Showing the first eight; more decompositions exist.
