Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80806, here are decompositions:

3 + 80803 = 80806
17 + 80789 = 80806
23 + 80783 = 80806
29 + 80777 = 80806
59 + 80747 = 80806
137 + 80669 = 80806
149 + 80657 = 80806
179 + 80627 = 80806

Showing the first eight; more decompositions exist.
