Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463796, here are decompositions:

17 + 31463779 = 31463796
29 + 31463767 = 31463796
37 + 31463759 = 31463796
53 + 31463743 = 31463796
79 + 31463717 = 31463796
83 + 31463713 = 31463796
107 + 31463689 = 31463796
263 + 31463533 = 31463796

Showing the first eight; more decompositions exist.
