Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463816, here are decompositions:

19 + 31463797 = 31463816
37 + 31463779 = 31463816
73 + 31463743 = 31463816
103 + 31463713 = 31463816
127 + 31463689 = 31463816
229 + 31463587 = 31463816
283 + 31463533 = 31463816
409 + 31463407 = 31463816

Showing the first eight; more decompositions exist.
