Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624832, here are decompositions:

3 + 31624829 = 31624832
79 + 31624753 = 31624832
193 + 31624639 = 31624832
241 + 31624591 = 31624832
409 + 31624423 = 31624832
691 + 31624141 = 31624832
829 + 31624003 = 31624832
853 + 31623979 = 31624832

Showing the first eight; more decompositions exist.
