Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66080, here are decompositions:

13 + 66067 = 66080
43 + 66037 = 66080
97 + 65983 = 66080
151 + 65929 = 66080
181 + 65899 = 66080
199 + 65881 = 66080
229 + 65851 = 66080
241 + 65839 = 66080

Showing the first eight; more decompositions exist.
