Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514732, here are decompositions:

43 + 31514689 = 31514732
61 + 31514671 = 31514732
79 + 31514653 = 31514732
103 + 31514629 = 31514732
181 + 31514551 = 31514732
199 + 31514533 = 31514732
283 + 31514449 = 31514732
313 + 31514419 = 31514732

Showing the first eight; more decompositions exist.
