Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549534, here are decompositions:

83 + 31549451 = 31549534
131 + 31549403 = 31549534
197 + 31549337 = 31549534
257 + 31549277 = 31549534
293 + 31549241 = 31549534
353 + 31549181 = 31549534
491 + 31549043 = 31549534
677 + 31548857 = 31549534

Showing the first eight; more decompositions exist.
