Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618068, here are decompositions:

5 + 31618063 = 31618068
7 + 31618061 = 31618068
11 + 31618057 = 31618068
19 + 31618049 = 31618068
67 + 31618001 = 31618068
71 + 31617997 = 31618068
101 + 31617967 = 31618068
107 + 31617961 = 31618068

Showing the first eight; more decompositions exist.
