Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999588, here are decompositions:

47 + 999541 = 999588
59 + 999529 = 999588
67 + 999521 = 999588
89 + 999499 = 999588
97 + 999491 = 999588
137 + 999451 = 999588
151 + 999437 = 999588
157 + 999431 = 999588

Showing the first eight; more decompositions exist.
