Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509146, here are decompositions:

23 + 509123 = 509146
59 + 509087 = 509146
83 + 509063 = 509146
173 + 508973 = 509146
227 + 508919 = 509146
233 + 508913 = 509146
347 + 508799 = 509146
419 + 508727 = 509146

Showing the first eight; more decompositions exist.
