Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466782, here are decompositions:

23 + 31466759 = 31466782
29 + 31466753 = 31466782
89 + 31466693 = 31466782
233 + 31466549 = 31466782
401 + 31466381 = 31466782
491 + 31466291 = 31466782
719 + 31466063 = 31466782
953 + 31465829 = 31466782

Showing the first eight; more decompositions exist.
