Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613056, here are decompositions:

3 + 31613053 = 31613056
29 + 31613027 = 31613056
317 + 31612739 = 31613056
389 + 31612667 = 31613056
467 + 31612589 = 31613056
509 + 31612547 = 31613056
569 + 31612487 = 31613056
743 + 31612313 = 31613056

Showing the first eight; more decompositions exist.
