Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449008, here are decompositions:

109 + 31448899 = 31449008
421 + 31448587 = 31449008
457 + 31448551 = 31449008
631 + 31448377 = 31449008
709 + 31448299 = 31449008
727 + 31448281 = 31449008
859 + 31448149 = 31449008
937 + 31448071 = 31449008

Showing the first eight; more decompositions exist.
