Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449458, here are decompositions:

37 + 31449421 = 31449458
97 + 31449361 = 31449458
199 + 31449259 = 31449458
211 + 31449247 = 31449458
331 + 31449127 = 31449458
421 + 31449037 = 31449458
619 + 31448839 = 31449458
739 + 31448719 = 31449458

Showing the first eight; more decompositions exist.
