Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999826, here are decompositions:

17 + 999809 = 999826
53 + 999773 = 999826
173 + 999653 = 999826
227 + 999599 = 999826
263 + 999563 = 999826
389 + 999437 = 999826
449 + 999377 = 999826
467 + 999359 = 999826

Showing the first eight; more decompositions exist.
