Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624732, here are decompositions:

59 + 31624673 = 31624732
71 + 31624661 = 31624732
89 + 31624643 = 31624732
101 + 31624631 = 31624732
173 + 31624559 = 31624732
383 + 31624349 = 31624732
389 + 31624343 = 31624732
401 + 31624331 = 31624732

Showing the first eight; more decompositions exist.
