Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999206, here are decompositions:

7 + 999199 = 999206
37 + 999169 = 999206
73 + 999133 = 999206
139 + 999067 = 999206
157 + 999049 = 999206
163 + 999043 = 999206
199 + 999007 = 999206
223 + 998983 = 999206

Showing the first eight; more decompositions exist.
