Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999218, here are decompositions:

19 + 999199 = 999218
37 + 999181 = 999218
127 + 999091 = 999218
151 + 999067 = 999218
211 + 999007 = 999218
229 + 998989 = 999218
271 + 998947 = 999218
277 + 998941 = 999218

Showing the first eight; more decompositions exist.
