Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613844, here are decompositions:

5 + 31613839 = 31613844
11 + 31613833 = 31613844
37 + 31613807 = 31613844
43 + 31613801 = 31613844
47 + 31613797 = 31613844
61 + 31613783 = 31613844
127 + 31613717 = 31613844
263 + 31613581 = 31613844

Showing the first eight; more decompositions exist.
