Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549300, here are decompositions:

23 + 31549277 = 31549300
59 + 31549241 = 31549300
257 + 31549043 = 31549300
281 + 31549019 = 31549300
317 + 31548983 = 31549300
347 + 31548953 = 31549300
443 + 31548857 = 31549300
557 + 31548743 = 31549300

Showing the first eight; more decompositions exist.
