Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449064, here are decompositions:

11 + 31449053 = 31449064
47 + 31449017 = 31449064
167 + 31448897 = 31449064
173 + 31448891 = 31449064
347 + 31448717 = 31449064
443 + 31448621 = 31449064
461 + 31448603 = 31449064
557 + 31448507 = 31449064

Showing the first eight; more decompositions exist.
