Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549348, here are decompositions:

11 + 31549337 = 31549348
71 + 31549277 = 31549348
107 + 31549241 = 31549348
167 + 31549181 = 31549348
491 + 31548857 = 31549348
599 + 31548749 = 31549348
797 + 31548551 = 31549348
821 + 31548527 = 31549348

Showing the first eight; more decompositions exist.
