Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999146, here are decompositions:

13 + 999133 = 999146
79 + 999067 = 999146
97 + 999049 = 999146
103 + 999043 = 999146
139 + 999007 = 999146
157 + 998989 = 999146
163 + 998983 = 999146
199 + 998947 = 999146

Showing the first eight; more decompositions exist.
