Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618134, here are decompositions:

7 + 31618127 = 31618134
13 + 31618121 = 31618134
71 + 31618063 = 31618134
73 + 31618061 = 31618134
131 + 31618003 = 31618134
137 + 31617997 = 31618134
167 + 31617967 = 31618134
173 + 31617961 = 31618134

Showing the first eight; more decompositions exist.
