Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660080, here are decompositions:

3 + 8660077 = 8660080
29 + 8660051 = 8660080
41 + 8660039 = 8660080
47 + 8660033 = 8660080
83 + 8659997 = 8660080
131 + 8659949 = 8660080
167 + 8659913 = 8660080
269 + 8659811 = 8660080

Showing the first eight; more decompositions exist.
