Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999228, here are decompositions:

7 + 999221 = 999228
11 + 999217 = 999228
29 + 999199 = 999228
47 + 999181 = 999228
59 + 999169 = 999228
79 + 999149 = 999228
127 + 999101 = 999228
137 + 999091 = 999228

Showing the first eight; more decompositions exist.
