Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31560362, here are decompositions:

19 + 31560343 = 31560362
283 + 31560079 = 31560362
373 + 31559989 = 31560362
541 + 31559821 = 31560362
643 + 31559719 = 31560362
709 + 31559653 = 31560362
739 + 31559623 = 31560362
919 + 31559443 = 31560362

Showing the first eight; more decompositions exist.
