Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549004, here are decompositions:

7 + 31548997 = 31549004
43 + 31548961 = 31549004
181 + 31548823 = 31549004
241 + 31548763 = 31549004
271 + 31548733 = 31549004
307 + 31548697 = 31549004
457 + 31548547 = 31549004
577 + 31548427 = 31549004

Showing the first eight; more decompositions exist.
