Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466274, here are decompositions:

11 + 31466263 = 31466274
17 + 31466257 = 31466274
23 + 31466251 = 31466274
41 + 31466233 = 31466274
53 + 31466221 = 31466274
67 + 31466207 = 31466274
101 + 31466173 = 31466274
131 + 31466143 = 31466274

Showing the first eight; more decompositions exist.
