Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494264, here are decompositions:

7 + 31494257 = 31494264
17 + 31494247 = 31494264
23 + 31494241 = 31494264
103 + 31494161 = 31494264
107 + 31494157 = 31494264
167 + 31494097 = 31494264
173 + 31494091 = 31494264
181 + 31494083 = 31494264

Showing the first eight; more decompositions exist.
