Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483916, here are decompositions:

3 + 31483913 = 31483916
97 + 31483819 = 31483916
109 + 31483807 = 31483916
127 + 31483789 = 31483916
157 + 31483759 = 31483916
193 + 31483723 = 31483916
367 + 31483549 = 31483916
463 + 31483453 = 31483916

Showing the first eight; more decompositions exist.
