Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446806, here are decompositions:

37 + 31446769 = 31446806
67 + 31446739 = 31446806
199 + 31446607 = 31446806
367 + 31446439 = 31446806
379 + 31446427 = 31446806
439 + 31446367 = 31446806
577 + 31446229 = 31446806
673 + 31446133 = 31446806

Showing the first eight; more decompositions exist.
