Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549204, here are decompositions:

3 + 31549201 = 31549204
23 + 31549181 = 31549204
251 + 31548953 = 31549204
347 + 31548857 = 31549204
461 + 31548743 = 31549204
563 + 31548641 = 31549204
641 + 31548563 = 31549204
653 + 31548551 = 31549204

Showing the first eight; more decompositions exist.
