Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549042, here are decompositions:

3 + 31549039 = 31549042
23 + 31549019 = 31549042
59 + 31548983 = 31549042
89 + 31548953 = 31549042
293 + 31548749 = 31549042
383 + 31548659 = 31549042
389 + 31548653 = 31549042
401 + 31548641 = 31549042

Showing the first eight; more decompositions exist.
