Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514172, here are decompositions:

13 + 31514159 = 31514172
23 + 31514149 = 31514172
29 + 31514143 = 31514172
59 + 31514113 = 31514172
71 + 31514101 = 31514172
113 + 31514059 = 31514172
149 + 31514023 = 31514172
229 + 31513943 = 31514172

Showing the first eight; more decompositions exist.
