Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549264, here are decompositions:

23 + 31549241 = 31549264
83 + 31549181 = 31549264
281 + 31548983 = 31549264
311 + 31548953 = 31549264
521 + 31548743 = 31549264
587 + 31548677 = 31549264
701 + 31548563 = 31549264
743 + 31548521 = 31549264

Showing the first eight; more decompositions exist.
