Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618114, here are decompositions:

53 + 31618061 = 31618114
71 + 31618043 = 31618114
113 + 31618001 = 31618114
173 + 31617941 = 31618114
251 + 31617863 = 31618114
317 + 31617797 = 31618114
401 + 31617713 = 31618114
617 + 31617497 = 31618114

Showing the first eight; more decompositions exist.
