Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80800, here are decompositions:

11 + 80789 = 80800
17 + 80783 = 80800
23 + 80777 = 80800
53 + 80747 = 80800
113 + 80687 = 80800
131 + 80669 = 80800
149 + 80651 = 80800
173 + 80627 = 80800

Showing the first eight; more decompositions exist.
