Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613684, here are decompositions:

61 + 31613623 = 31613684
103 + 31613581 = 31613684
283 + 31613401 = 31613684
307 + 31613377 = 31613684
457 + 31613227 = 31613684
541 + 31613143 = 31613684
547 + 31613137 = 31613684
577 + 31613107 = 31613684

Showing the first eight; more decompositions exist.
