Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 516826, here are decompositions:

5 + 516821 = 516826
113 + 516713 = 516826
137 + 516689 = 516826
173 + 516653 = 516826
227 + 516599 = 516826
239 + 516587 = 516826
263 + 516563 = 516826
389 + 516437 = 516826

Showing the first eight; more decompositions exist.
