Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999556, here are decompositions:

3 + 999553 = 999556
167 + 999389 = 999556
179 + 999377 = 999556
197 + 999359 = 999556
227 + 999329 = 999556
269 + 999287 = 999556
317 + 999239 = 999556
587 + 998969 = 999556

Showing the first eight; more decompositions exist.
