Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514166, here are decompositions:

7 + 31514159 = 31514166
17 + 31514149 = 31514166
23 + 31514143 = 31514166
53 + 31514113 = 31514166
107 + 31514059 = 31514166
179 + 31513987 = 31514166
199 + 31513967 = 31514166
223 + 31513943 = 31514166

Showing the first eight; more decompositions exist.
