Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448608, here are decompositions:

5 + 31448603 = 31448608
29 + 31448579 = 31448608
89 + 31448519 = 31448608
101 + 31448507 = 31448608
227 + 31448381 = 31448608
239 + 31448369 = 31448608
311 + 31448297 = 31448608
467 + 31448141 = 31448608

Showing the first eight; more decompositions exist.
