Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448614, here are decompositions:

11 + 31448603 = 31448614
107 + 31448507 = 31448614
167 + 31448447 = 31448614
191 + 31448423 = 31448614
233 + 31448381 = 31448614
293 + 31448321 = 31448614
311 + 31448303 = 31448614
317 + 31448297 = 31448614

Showing the first eight; more decompositions exist.
