Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466256, here are decompositions:

5 + 31466251 = 31466256
7 + 31466249 = 31466256
23 + 31466233 = 31466256
83 + 31466173 = 31466256
113 + 31466143 = 31466256
137 + 31466119 = 31466256
149 + 31466107 = 31466256
167 + 31466089 = 31466256

Showing the first eight; more decompositions exist.
