Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999508, here are decompositions:

17 + 999491 = 999508
71 + 999437 = 999508
131 + 999377 = 999508
137 + 999371 = 999508
149 + 999359 = 999508
179 + 999329 = 999508
239 + 999269 = 999508
269 + 999239 = 999508

Showing the first eight; more decompositions exist.
