Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466372, here are decompositions:

31 + 31466341 = 31466372
43 + 31466329 = 31466372
109 + 31466263 = 31466372
139 + 31466233 = 31466372
151 + 31466221 = 31466372
199 + 31466173 = 31466372
229 + 31466143 = 31466372
271 + 31466101 = 31466372

Showing the first eight; more decompositions exist.
