Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514232, here are decompositions:

11 + 31514221 = 31514232
41 + 31514191 = 31514232
73 + 31514159 = 31514232
83 + 31514149 = 31514232
89 + 31514143 = 31514232
131 + 31514101 = 31514232
151 + 31514081 = 31514232
173 + 31514059 = 31514232

Showing the first eight; more decompositions exist.
