Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999678, here are decompositions:

7 + 999671 = 999678
11 + 999667 = 999678
47 + 999631 = 999678
67 + 999611 = 999678
79 + 999599 = 999678
137 + 999541 = 999678
149 + 999529 = 999678
157 + 999521 = 999678

Showing the first eight; more decompositions exist.
