Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80760, here are decompositions:

11 + 80749 = 80760
13 + 80747 = 80760
23 + 80737 = 80760
47 + 80713 = 80760
59 + 80701 = 80760
73 + 80687 = 80760
79 + 80681 = 80760
83 + 80677 = 80760

Showing the first eight; more decompositions exist.
