Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613504, here are decompositions:

67 + 31613437 = 31613504
103 + 31613401 = 31613504
127 + 31613377 = 31613504
163 + 31613341 = 31613504
277 + 31613227 = 31613504
313 + 31613191 = 31613504
367 + 31613137 = 31613504
397 + 31613107 = 31613504

Showing the first eight; more decompositions exist.
