Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549258, here are decompositions:

17 + 31549241 = 31549258
239 + 31549019 = 31549258
401 + 31548857 = 31549258
491 + 31548767 = 31549258
509 + 31548749 = 31549258
599 + 31548659 = 31549258
617 + 31548641 = 31549258
827 + 31548431 = 31549258

Showing the first eight; more decompositions exist.
