Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448866, here are decompositions:

3 + 31448863 = 31448866
149 + 31448717 = 31448866
167 + 31448699 = 31448866
173 + 31448693 = 31448866
227 + 31448639 = 31448866
263 + 31448603 = 31448866
347 + 31448519 = 31448866
359 + 31448507 = 31448866

Showing the first eight; more decompositions exist.
