Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80866, here are decompositions:

3 + 80863 = 80866
17 + 80849 = 80866
47 + 80819 = 80866
83 + 80783 = 80866
89 + 80777 = 80866
179 + 80687 = 80866
197 + 80669 = 80866
239 + 80627 = 80866

Showing the first eight; more decompositions exist.
