Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990084, here are decompositions:

31 + 990053 = 990084
41 + 990043 = 990084
47 + 990037 = 990084
61 + 990023 = 990084
71 + 990013 = 990084
83 + 990001 = 990084
103 + 989981 = 990084
107 + 989977 = 990084

Showing the first eight; more decompositions exist.
