Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80836, here are decompositions:

3 + 80833 = 80836
5 + 80831 = 80836
17 + 80819 = 80836
47 + 80789 = 80836
53 + 80783 = 80836
59 + 80777 = 80836
89 + 80747 = 80836
149 + 80687 = 80836

Showing the first eight; more decompositions exist.
