Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999286, here are decompositions:

17 + 999269 = 999286
47 + 999239 = 999286
53 + 999233 = 999286
137 + 999149 = 999286
257 + 999029 = 999286
263 + 999023 = 999286
317 + 998969 = 999286
359 + 998927 = 999286

Showing the first eight; more decompositions exist.
