Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483938, here are decompositions:

11 + 31483927 = 31483938
19 + 31483919 = 31483938
61 + 31483877 = 31483938
67 + 31483871 = 31483938
97 + 31483841 = 31483938
131 + 31483807 = 31483938
137 + 31483801 = 31483938
139 + 31483799 = 31483938

Showing the first eight; more decompositions exist.
