Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559756, here are decompositions:

37 + 31559719 = 31559756
79 + 31559677 = 31559756
97 + 31559659 = 31559756
103 + 31559653 = 31559756
313 + 31559443 = 31559756
373 + 31559383 = 31559756
439 + 31559317 = 31559756
607 + 31559149 = 31559756

Showing the first eight; more decompositions exist.
