Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 89806, here are decompositions:

23 + 89783 = 89806
47 + 89759 = 89806
53 + 89753 = 89806
137 + 89669 = 89806
149 + 89657 = 89806
173 + 89633 = 89806
179 + 89627 = 89806
239 + 89567 = 89806

Showing the first eight; more decompositions exist.
