Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483842, here are decompositions:

23 + 31483819 = 31483842
41 + 31483801 = 31483842
43 + 31483799 = 31483842
53 + 31483789 = 31483842
83 + 31483759 = 31483842
109 + 31483733 = 31483842
151 + 31483691 = 31483842
179 + 31483663 = 31483842

Showing the first eight; more decompositions exist.
