Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448574, here are decompositions:

23 + 31448551 = 31448574
41 + 31448533 = 31448574
67 + 31448507 = 31448574
127 + 31448447 = 31448574
151 + 31448423 = 31448574
193 + 31448381 = 31448574
197 + 31448377 = 31448574
251 + 31448323 = 31448574

Showing the first eight; more decompositions exist.
