Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549764, here are decompositions:

11 + 31549753 = 31549764
13 + 31549751 = 31549764
31 + 31549733 = 31549764
47 + 31549717 = 31549764
73 + 31549691 = 31549764
97 + 31549667 = 31549764
101 + 31549663 = 31549764
157 + 31549607 = 31549764

Showing the first eight; more decompositions exist.
