Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624518, here are decompositions:

7 + 31624511 = 31624518
11 + 31624507 = 31624518
41 + 31624477 = 31624518
61 + 31624457 = 31624518
89 + 31624429 = 31624518
131 + 31624387 = 31624518
151 + 31624367 = 31624518
179 + 31624339 = 31624518

Showing the first eight; more decompositions exist.
