Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618096, here are decompositions:

47 + 31618049 = 31618096
53 + 31618043 = 31618096
137 + 31617959 = 31618096
197 + 31617899 = 31618096
233 + 31617863 = 31618096
269 + 31617827 = 31618096
383 + 31617713 = 31618096
467 + 31617629 = 31618096

Showing the first eight; more decompositions exist.
