Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449464, here are decompositions:

43 + 31449421 = 31449464
61 + 31449403 = 31449464
103 + 31449361 = 31449464
223 + 31449241 = 31449464
337 + 31449127 = 31449464
421 + 31449043 = 31449464
601 + 31448863 = 31449464
643 + 31448821 = 31449464

Showing the first eight; more decompositions exist.
