Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90984, here are decompositions:

7 + 90977 = 90984
13 + 90971 = 90984
37 + 90947 = 90984
53 + 90931 = 90984
67 + 90917 = 90984
73 + 90911 = 90984
83 + 90901 = 90984
97 + 90887 = 90984

Showing the first eight; more decompositions exist.
