Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981084, here are decompositions:

7 + 981077 = 981084
11 + 981073 = 981084
17 + 981067 = 981084
23 + 981061 = 981084
47 + 981037 = 981084
61 + 981023 = 981084
67 + 981017 = 981084
73 + 981011 = 981084

Showing the first eight; more decompositions exist.
