Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466268, here are decompositions:

5 + 31466263 = 31466268
11 + 31466257 = 31466268
17 + 31466251 = 31466268
19 + 31466249 = 31466268
47 + 31466221 = 31466268
61 + 31466207 = 31466268
131 + 31466137 = 31466268
149 + 31466119 = 31466268

Showing the first eight; more decompositions exist.
