Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613570, here are decompositions:

19 + 31613551 = 31613570
31 + 31613539 = 31613570
193 + 31613377 = 31613570
229 + 31613341 = 31613570
379 + 31613191 = 31613570
433 + 31613137 = 31613570
463 + 31613107 = 31613570
601 + 31612969 = 31613570

Showing the first eight; more decompositions exist.
