Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613948, here are decompositions:

109 + 31613839 = 31613948
151 + 31613797 = 31613948
229 + 31613719 = 31613948
367 + 31613581 = 31613948
397 + 31613551 = 31613948
409 + 31613539 = 31613948
547 + 31613401 = 31613948
571 + 31613377 = 31613948

Showing the first eight; more decompositions exist.
