Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514376, here are decompositions:

67 + 31514309 = 31514376
79 + 31514297 = 31514376
109 + 31514267 = 31514376
137 + 31514239 = 31514376
227 + 31514149 = 31514376
233 + 31514143 = 31514376
263 + 31514113 = 31514376
317 + 31514059 = 31514376

Showing the first eight; more decompositions exist.
