Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999690, here are decompositions:

7 + 999683 = 999690
19 + 999671 = 999690
23 + 999667 = 999690
37 + 999653 = 999690
59 + 999631 = 999690
67 + 999623 = 999690
79 + 999611 = 999690
127 + 999563 = 999690

Showing the first eight; more decompositions exist.
