Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618056, here are decompositions:

7 + 31618049 = 31618056
13 + 31618043 = 31618056
53 + 31618003 = 31618056
59 + 31617997 = 31618056
89 + 31617967 = 31618056
97 + 31617959 = 31618056
103 + 31617953 = 31618056
157 + 31617899 = 31618056

Showing the first eight; more decompositions exist.
