Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86080, here are decompositions:

3 + 86077 = 86080
11 + 86069 = 86080
53 + 86027 = 86080
89 + 85991 = 86080
149 + 85931 = 86080
191 + 85889 = 86080
227 + 85853 = 86080
233 + 85847 = 86080

Showing the first eight; more decompositions exist.
