Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466212, here are decompositions:

5 + 31466207 = 31466212
149 + 31466063 = 31466212
233 + 31465979 = 31466212
383 + 31465829 = 31466212
431 + 31465781 = 31466212
563 + 31465649 = 31466212
593 + 31465619 = 31466212
641 + 31465571 = 31466212

Showing the first eight; more decompositions exist.
