Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618074, here are decompositions:

11 + 31618063 = 31618074
13 + 31618061 = 31618074
17 + 31618057 = 31618074
31 + 31618043 = 31618074
71 + 31618003 = 31618074
73 + 31618001 = 31618074
107 + 31617967 = 31618074
113 + 31617961 = 31618074

Showing the first eight; more decompositions exist.
