Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 516838, here are decompositions:

17 + 516821 = 516838
137 + 516701 = 516838
149 + 516689 = 516838
227 + 516611 = 516838
239 + 516599 = 516838
251 + 516587 = 516838
317 + 516521 = 516838
389 + 516449 = 516838

Showing the first eight; more decompositions exist.
