Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20080, here are decompositions:

17 + 20063 = 20080
29 + 20051 = 20080
59 + 20021 = 20080
83 + 19997 = 20080
89 + 19991 = 20080
101 + 19979 = 20080
107 + 19973 = 20080
131 + 19949 = 20080

Showing the first eight; more decompositions exist.
