Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624410, here are decompositions:

23 + 31624387 = 31624410
43 + 31624367 = 31624410
47 + 31624363 = 31624410
53 + 31624357 = 31624410
61 + 31624349 = 31624410
67 + 31624343 = 31624410
71 + 31624339 = 31624410
73 + 31624337 = 31624410

Showing the first eight; more decompositions exist.
