Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990038, here are decompositions:

37 + 990001 = 990038
61 + 989977 = 990038
67 + 989971 = 990038
79 + 989959 = 990038
109 + 989929 = 990038
151 + 989887 = 990038
199 + 989839 = 990038
211 + 989827 = 990038

Showing the first eight; more decompositions exist.
