Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624446, here are decompositions:

17 + 31624429 = 31624446
23 + 31624423 = 31624446
59 + 31624387 = 31624446
79 + 31624367 = 31624446
83 + 31624363 = 31624446
89 + 31624357 = 31624446
97 + 31624349 = 31624446
103 + 31624343 = 31624446

Showing the first eight; more decompositions exist.
