Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613510, here are decompositions:

73 + 31613437 = 31613510
109 + 31613401 = 31613510
127 + 31613383 = 31613510
283 + 31613227 = 31613510
367 + 31613143 = 31613510
373 + 31613137 = 31613510
457 + 31613053 = 31613510
541 + 31612969 = 31613510

Showing the first eight; more decompositions exist.
