Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514318, here are decompositions:

79 + 31514239 = 31514318
97 + 31514221 = 31514318
127 + 31514191 = 31514318
331 + 31513987 = 31514318
439 + 31513879 = 31514318
487 + 31513831 = 31514318
499 + 31513819 = 31514318
739 + 31513579 = 31514318

Showing the first eight; more decompositions exist.
