Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449062, here are decompositions:

19 + 31449043 = 31449062
163 + 31448899 = 31449062
199 + 31448863 = 31449062
223 + 31448839 = 31449062
241 + 31448821 = 31449062
349 + 31448713 = 31449062
613 + 31448449 = 31449062
739 + 31448323 = 31449062

Showing the first eight; more decompositions exist.
