Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519768, here are decompositions:

31 + 519737 = 519768
101 + 519667 = 519768
149 + 519619 = 519768
157 + 519611 = 519768
181 + 519587 = 519768
191 + 519577 = 519768
229 + 519539 = 519768
241 + 519527 = 519768

Showing the first eight; more decompositions exist.
