Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999140, here are decompositions:

7 + 999133 = 999140
73 + 999067 = 999140
97 + 999043 = 999140
151 + 998989 = 999140
157 + 998983 = 999140
193 + 998947 = 999140
199 + 998941 = 999140
223 + 998917 = 999140

Showing the first eight; more decompositions exist.
