Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618484, here are decompositions:

43 + 31618441 = 31618484
61 + 31618423 = 31618484
421 + 31618063 = 31618484
487 + 31617997 = 31618484
523 + 31617961 = 31618484
607 + 31617877 = 31618484
613 + 31617871 = 31618484
631 + 31617853 = 31618484

Showing the first eight; more decompositions exist.
