Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483776, here are decompositions:

17 + 31483759 = 31483776
43 + 31483733 = 31483776
53 + 31483723 = 31483776
113 + 31483663 = 31483776
127 + 31483649 = 31483776
179 + 31483597 = 31483776
193 + 31483583 = 31483776
199 + 31483577 = 31483776

Showing the first eight; more decompositions exist.
