Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549070, here are decompositions:

19 + 31549051 = 31549070
31 + 31549039 = 31549070
61 + 31549009 = 31549070
73 + 31548997 = 31549070
109 + 31548961 = 31549070
199 + 31548871 = 31549070
307 + 31548763 = 31549070
313 + 31548757 = 31549070

Showing the first eight; more decompositions exist.
