Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999656, here are decompositions:

3 + 999653 = 999656
43 + 999613 = 999656
103 + 999553 = 999656
127 + 999529 = 999656
157 + 999499 = 999656
223 + 999433 = 999656
349 + 999307 = 999656
439 + 999217 = 999656

Showing the first eight; more decompositions exist.
