Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559936, here are decompositions:

103 + 31559833 = 31559936
127 + 31559809 = 31559936
277 + 31559659 = 31559936
283 + 31559653 = 31559936
313 + 31559623 = 31559936
523 + 31559413 = 31559936
619 + 31559317 = 31559936
673 + 31559263 = 31559936

Showing the first eight; more decompositions exist.
