Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514564, here are decompositions:

13 + 31514551 = 31514564
31 + 31514533 = 31514564
163 + 31514401 = 31514564
373 + 31514191 = 31514564
421 + 31514143 = 31514564
463 + 31514101 = 31514564
541 + 31514023 = 31514564
577 + 31513987 = 31514564

Showing the first eight; more decompositions exist.
