Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005598, here are decompositions:

5 + 1005593 = 1005598
17 + 1005581 = 1005598
47 + 1005551 = 1005598
71 + 1005527 = 1005598
131 + 1005467 = 1005598
227 + 1005371 = 1005598
239 + 1005359 = 1005598
281 + 1005317 = 1005598

Showing the first eight; more decompositions exist.
