Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005286, here are decompositions:

17 + 1005269 = 1005286
47 + 1005239 = 1005286
83 + 1005203 = 1005286
179 + 1005107 = 1005286
257 + 1005029 = 1005286
383 + 1004903 = 1005286
563 + 1004723 = 1005286
599 + 1004687 = 1005286

Showing the first eight; more decompositions exist.
