Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999586, here are decompositions:

23 + 999563 = 999586
149 + 999437 = 999586
197 + 999389 = 999586
227 + 999359 = 999586
257 + 999329 = 999586
317 + 999269 = 999586
347 + 999239 = 999586
353 + 999233 = 999586

Showing the first eight; more decompositions exist.
