Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549848, here are decompositions:

19 + 31549829 = 31549848
47 + 31549801 = 31549848
67 + 31549781 = 31549848
97 + 31549751 = 31549848
131 + 31549717 = 31549848
157 + 31549691 = 31549848
181 + 31549667 = 31549848
199 + 31549649 = 31549848

Showing the first eight; more decompositions exist.
