Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514118, here are decompositions:

5 + 31514113 = 31514118
17 + 31514101 = 31514118
37 + 31514081 = 31514118
59 + 31514059 = 31514118
131 + 31513987 = 31514118
151 + 31513967 = 31514118
191 + 31513927 = 31514118
227 + 31513891 = 31514118

Showing the first eight; more decompositions exist.
