Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999898, here are decompositions:

89 + 999809 = 999898
149 + 999749 = 999898
227 + 999671 = 999898
461 + 999437 = 999898
467 + 999431 = 999898
509 + 999389 = 999898
521 + 999377 = 999898
569 + 999329 = 999898

Showing the first eight; more decompositions exist.
