Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999786, here are decompositions:

13 + 999773 = 999786
17 + 999769 = 999786
23 + 999763 = 999786
37 + 999749 = 999786
59 + 999727 = 999786
103 + 999683 = 999786
163 + 999623 = 999786
173 + 999613 = 999786

Showing the first eight; more decompositions exist.
