Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618094, here are decompositions:

31 + 31618063 = 31618094
37 + 31618057 = 31618094
97 + 31617997 = 31618094
127 + 31617967 = 31618094
223 + 31617871 = 31618094
241 + 31617853 = 31618094
283 + 31617811 = 31618094
331 + 31617763 = 31618094

Showing the first eight; more decompositions exist.
