Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549002, here are decompositions:

5 + 31548997 = 31549002
19 + 31548983 = 31549002
41 + 31548961 = 31549002
131 + 31548871 = 31549002
179 + 31548823 = 31549002
239 + 31548763 = 31549002
263 + 31548739 = 31549002
269 + 31548733 = 31549002

Showing the first eight; more decompositions exist.
