Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999406, here are decompositions:

17 + 999389 = 999406
29 + 999377 = 999406
47 + 999359 = 999406
137 + 999269 = 999406
167 + 999239 = 999406
173 + 999233 = 999406
257 + 999149 = 999406
383 + 999023 = 999406

Showing the first eight; more decompositions exist.
