Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549804, here are decompositions:

3 + 31549801 = 31549804
5 + 31549799 = 31549804
23 + 31549781 = 31549804
53 + 31549751 = 31549804
71 + 31549733 = 31549804
113 + 31549691 = 31549804
137 + 31549667 = 31549804
197 + 31549607 = 31549804

Showing the first eight; more decompositions exist.
