Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514214, here are decompositions:

23 + 31514191 = 31514214
71 + 31514143 = 31514214
101 + 31514113 = 31514214
113 + 31514101 = 31514214
191 + 31514023 = 31514214
227 + 31513987 = 31514214
257 + 31513957 = 31514214
271 + 31513943 = 31514214

Showing the first eight; more decompositions exist.
