Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990086, here are decompositions:

43 + 990043 = 990086
73 + 990013 = 990086
109 + 989977 = 990086
127 + 989959 = 990086
157 + 989929 = 990086
199 + 989887 = 990086
283 + 989803 = 990086
337 + 989749 = 990086

Showing the first eight; more decompositions exist.
