Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514218, here are decompositions:

59 + 31514159 = 31514218
137 + 31514081 = 31514218
251 + 31513967 = 31514218
401 + 31513817 = 31514218
431 + 31513787 = 31514218
479 + 31513739 = 31514218
509 + 31513709 = 31514218
521 + 31513697 = 31514218

Showing the first eight; more decompositions exist.
