Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618592, here are decompositions:

13 + 31618579 = 31618592
43 + 31618549 = 31618592
73 + 31618519 = 31618592
151 + 31618441 = 31618592
631 + 31617961 = 31618592
739 + 31617853 = 31618592
829 + 31617763 = 31618592
919 + 31617673 = 31618592

Showing the first eight; more decompositions exist.
