Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999216, here are decompositions:

17 + 999199 = 999216
47 + 999169 = 999216
67 + 999149 = 999216
83 + 999133 = 999216
149 + 999067 = 999216
167 + 999049 = 999216
173 + 999043 = 999216
193 + 999023 = 999216

Showing the first eight; more decompositions exist.
