Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483966, here are decompositions:

47 + 31483919 = 31483966
53 + 31483913 = 31483966
83 + 31483883 = 31483966
89 + 31483877 = 31483966
167 + 31483799 = 31483966
233 + 31483733 = 31483966
317 + 31483649 = 31483966
383 + 31483583 = 31483966

Showing the first eight; more decompositions exist.
