Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 89820, here are decompositions:

11 + 89809 = 89820
23 + 89797 = 89820
37 + 89783 = 89820
41 + 89779 = 89820
53 + 89767 = 89820
61 + 89759 = 89820
67 + 89753 = 89820
131 + 89689 = 89820

Showing the first eight; more decompositions exist.
