Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483836, here are decompositions:

17 + 31483819 = 31483836
29 + 31483807 = 31483836
37 + 31483799 = 31483836
47 + 31483789 = 31483836
103 + 31483733 = 31483836
113 + 31483723 = 31483836
173 + 31483663 = 31483836
239 + 31483597 = 31483836

Showing the first eight; more decompositions exist.
