Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466392, here are decompositions:

3 + 31466389 = 31466392
5 + 31466387 = 31466392
11 + 31466381 = 31466392
101 + 31466291 = 31466392
389 + 31466003 = 31466392
563 + 31465829 = 31466392
719 + 31465673 = 31466392
743 + 31465649 = 31466392

Showing the first eight; more decompositions exist.
