Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999212, here are decompositions:

13 + 999199 = 999212
31 + 999181 = 999212
43 + 999169 = 999212
79 + 999133 = 999212
163 + 999049 = 999212
223 + 998989 = 999212
229 + 998983 = 999212
271 + 998941 = 999212

Showing the first eight; more decompositions exist.
