Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999688, here are decompositions:

5 + 999683 = 999688
17 + 999671 = 999688
89 + 999599 = 999688
167 + 999521 = 999688
197 + 999491 = 999688
251 + 999437 = 999688
257 + 999431 = 999688
311 + 999377 = 999688

Showing the first eight; more decompositions exist.
