Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613984, here are decompositions:

151 + 31613833 = 31613984
433 + 31613551 = 31613984
547 + 31613437 = 31613984
601 + 31613383 = 31613984
607 + 31613377 = 31613984
643 + 31613341 = 31613984
757 + 31613227 = 31613984
877 + 31613107 = 31613984

Showing the first eight; more decompositions exist.
