Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618936, here are decompositions:

53 + 31618883 = 31618936
113 + 31618823 = 31618936
233 + 31618703 = 31618936
389 + 31618547 = 31618936
617 + 31618319 = 31618936
647 + 31618289 = 31618936
743 + 31618193 = 31618936
773 + 31618163 = 31618936

Showing the first eight; more decompositions exist.
