Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999558, here are decompositions:

5 + 999553 = 999558
17 + 999541 = 999558
29 + 999529 = 999558
37 + 999521 = 999558
59 + 999499 = 999558
67 + 999491 = 999558
107 + 999451 = 999558
127 + 999431 = 999558

Showing the first eight; more decompositions exist.
