Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466270, here are decompositions:

7 + 31466263 = 31466270
13 + 31466257 = 31466270
19 + 31466251 = 31466270
37 + 31466233 = 31466270
97 + 31466173 = 31466270
127 + 31466143 = 31466270
151 + 31466119 = 31466270
163 + 31466107 = 31466270

Showing the first eight; more decompositions exist.
