Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519766, here are decompositions:

29 + 519737 = 519766
53 + 519713 = 519766
83 + 519683 = 519766
179 + 519587 = 519766
227 + 519539 = 519766
239 + 519527 = 519766
257 + 519509 = 519766
353 + 519413 = 519766

Showing the first eight; more decompositions exist.
