Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613516, here are decompositions:

3 + 31613513 = 31613516
79 + 31613437 = 31613516
139 + 31613377 = 31613516
373 + 31613143 = 31613516
379 + 31613137 = 31613516
397 + 31613119 = 31613516
409 + 31613107 = 31613516
463 + 31613053 = 31613516

Showing the first eight; more decompositions exist.
