Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998028, here are decompositions:

11 + 998017 = 998028
19 + 998009 = 998028
37 + 997991 = 998028
67 + 997961 = 998028
79 + 997949 = 998028
131 + 997897 = 998028
137 + 997891 = 998028
139 + 997889 = 998028

Showing the first eight; more decompositions exist.
