Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449146, here are decompositions:

19 + 31449127 = 31449146
103 + 31449043 = 31449146
109 + 31449037 = 31449146
283 + 31448863 = 31449146
307 + 31448839 = 31449146
433 + 31448713 = 31449146
439 + 31448707 = 31449146
499 + 31448647 = 31449146

Showing the first eight; more decompositions exist.
