Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624672, here are decompositions:

11 + 31624661 = 31624672
29 + 31624643 = 31624672
41 + 31624631 = 31624672
59 + 31624613 = 31624672
113 + 31624559 = 31624672
389 + 31624283 = 31624672
659 + 31624013 = 31624672
683 + 31623989 = 31624672

Showing the first eight; more decompositions exist.
