Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 516728, here are decompositions:

7 + 516721 = 516728
19 + 516709 = 516728
109 + 516619 = 516728
139 + 516589 = 516728
211 + 516517 = 516728
229 + 516499 = 516728
271 + 516457 = 516728
307 + 516421 = 516728

Showing the first eight; more decompositions exist.
