Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18080, here are decompositions:

3 + 18077 = 18080
19 + 18061 = 18080
31 + 18049 = 18080
37 + 18043 = 18080
67 + 18013 = 18080
103 + 17977 = 18080
109 + 17971 = 18080
151 + 17929 = 18080

Showing the first eight; more decompositions exist.
