Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466572, here are decompositions:

23 + 31466549 = 31466572
191 + 31466381 = 31466572
281 + 31466291 = 31466572
509 + 31466063 = 31466572
521 + 31466051 = 31466572
569 + 31466003 = 31466572
593 + 31465979 = 31466572
743 + 31465829 = 31466572

Showing the first eight; more decompositions exist.
