Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448334, here are decompositions:

11 + 31448323 = 31448334
13 + 31448321 = 31448334
31 + 31448303 = 31448334
37 + 31448297 = 31448334
41 + 31448293 = 31448334
53 + 31448281 = 31448334
101 + 31448233 = 31448334
163 + 31448171 = 31448334

Showing the first eight; more decompositions exist.
