Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466748, here are decompositions:

17 + 31466731 = 31466748
29 + 31466719 = 31466748
41 + 31466707 = 31466748
59 + 31466689 = 31466748
151 + 31466597 = 31466748
199 + 31466549 = 31466748
347 + 31466401 = 31466748
359 + 31466389 = 31466748

Showing the first eight; more decompositions exist.
