Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 89790, here are decompositions:

7 + 89783 = 89790
11 + 89779 = 89790
23 + 89767 = 89790
31 + 89759 = 89790
37 + 89753 = 89790
101 + 89689 = 89790
109 + 89681 = 89790
131 + 89659 = 89790

Showing the first eight; more decompositions exist.
