Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613456, here are decompositions:

19 + 31613437 = 31613456
73 + 31613383 = 31613456
79 + 31613377 = 31613456
229 + 31613227 = 31613456
313 + 31613143 = 31613456
337 + 31613119 = 31613456
349 + 31613107 = 31613456
487 + 31612969 = 31613456

Showing the first eight; more decompositions exist.
