Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80686, here are decompositions:

3 + 80683 = 80686
5 + 80681 = 80686
17 + 80669 = 80686
29 + 80657 = 80686
59 + 80627 = 80686
83 + 80603 = 80686
149 + 80537 = 80686
173 + 80513 = 80686

Showing the first eight; more decompositions exist.
