Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514238, here are decompositions:

17 + 31514221 = 31514238
47 + 31514191 = 31514238
79 + 31514159 = 31514238
89 + 31514149 = 31514238
137 + 31514101 = 31514238
157 + 31514081 = 31514238
179 + 31514059 = 31514238
251 + 31513987 = 31514238

Showing the first eight; more decompositions exist.
