Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449214, here are decompositions:

23 + 31449191 = 31449214
131 + 31449083 = 31449214
197 + 31449017 = 31449214
227 + 31448987 = 31449214
311 + 31448903 = 31449214
317 + 31448897 = 31449214
521 + 31448693 = 31449214
593 + 31448621 = 31449214

Showing the first eight; more decompositions exist.
