Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624664, here are decompositions:

3 + 31624661 = 31624664
37 + 31624627 = 31624664
67 + 31624597 = 31624664
73 + 31624591 = 31624664
157 + 31624507 = 31624664
241 + 31624423 = 31624664
277 + 31624387 = 31624664
307 + 31624357 = 31624664

Showing the first eight; more decompositions exist.
