Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483806, here are decompositions:

5 + 31483801 = 31483806
7 + 31483799 = 31483806
17 + 31483789 = 31483806
47 + 31483759 = 31483806
73 + 31483733 = 31483806
83 + 31483723 = 31483806
157 + 31483649 = 31483806
223 + 31483583 = 31483806

Showing the first eight; more decompositions exist.
