Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102080, here are decompositions:

3 + 102077 = 102080
19 + 102061 = 102080
37 + 102043 = 102080
61 + 102019 = 102080
67 + 102013 = 102080
79 + 102001 = 102080
103 + 101977 = 102080
151 + 101929 = 102080

Showing the first eight; more decompositions exist.
