Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999028, here are decompositions:

5 + 999023 = 999028
59 + 998969 = 999028
71 + 998957 = 999028
101 + 998927 = 999028
131 + 998897 = 999028
167 + 998861 = 999028
197 + 998831 = 999028
269 + 998759 = 999028

Showing the first eight; more decompositions exist.
