Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613658, here are decompositions:

19 + 31613639 = 31613658
29 + 31613629 = 31613658
31 + 31613627 = 31613658
79 + 31613579 = 31613658
107 + 31613551 = 31613658
257 + 31613401 = 31613658
281 + 31613377 = 31613658
317 + 31613341 = 31613658

Showing the first eight; more decompositions exist.
