Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549306, here are decompositions:

29 + 31549277 = 31549306
263 + 31549043 = 31549306
353 + 31548953 = 31549306
449 + 31548857 = 31549306
557 + 31548749 = 31549306
563 + 31548743 = 31549306
647 + 31548659 = 31549306
653 + 31548653 = 31549306

Showing the first eight; more decompositions exist.
