Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514302, here are decompositions:

5 + 31514297 = 31514302
11 + 31514291 = 31514302
41 + 31514261 = 31514302
359 + 31513943 = 31514302
509 + 31513793 = 31514302
563 + 31513739 = 31514302
593 + 31513709 = 31514302
641 + 31513661 = 31514302

Showing the first eight; more decompositions exist.
