Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624682, here are decompositions:

43 + 31624639 = 31624682
541 + 31624141 = 31624682
613 + 31624069 = 31624682
751 + 31623931 = 31624682
1093 + 31623589 = 31624682
1171 + 31623511 = 31624682
1201 + 31623481 = 31624682
1459 + 31623223 = 31624682

Showing the first eight; more decompositions exist.
