Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514128, here are decompositions:

47 + 31514081 = 31514128
251 + 31513877 = 31514128
311 + 31513817 = 31514128
389 + 31513739 = 31514128
419 + 31513709 = 31514128
431 + 31513697 = 31514128
461 + 31513667 = 31514128
467 + 31513661 = 31514128

Showing the first eight; more decompositions exist.
