Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468266, here are decompositions:

7 + 31468259 = 31468266
19 + 31468247 = 31468266
23 + 31468243 = 31468266
43 + 31468223 = 31468266
97 + 31468169 = 31468266
107 + 31468159 = 31468266
199 + 31468067 = 31468266
239 + 31468027 = 31468266

Showing the first eight; more decompositions exist.
