Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999260, here are decompositions:

43 + 999217 = 999260
61 + 999199 = 999260
79 + 999181 = 999260
127 + 999133 = 999260
193 + 999067 = 999260
211 + 999049 = 999260
271 + 998989 = 999260
277 + 998983 = 999260

Showing the first eight; more decompositions exist.
