Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483818, here are decompositions:

11 + 31483807 = 31483818
17 + 31483801 = 31483818
19 + 31483799 = 31483818
29 + 31483789 = 31483818
59 + 31483759 = 31483818
127 + 31483691 = 31483818
241 + 31483577 = 31483818
269 + 31483549 = 31483818

Showing the first eight; more decompositions exist.
