Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448494, here are decompositions:

47 + 31448447 = 31448494
71 + 31448423 = 31448494
113 + 31448381 = 31448494
173 + 31448321 = 31448494
191 + 31448303 = 31448494
197 + 31448297 = 31448494
293 + 31448201 = 31448494
353 + 31448141 = 31448494

Showing the first eight; more decompositions exist.
