Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164080, here are decompositions:

23 + 164057 = 164080
29 + 164051 = 164080
41 + 164039 = 164080
83 + 163997 = 164080
89 + 163991 = 164080
101 + 163979 = 164080
107 + 163973 = 164080
179 + 163901 = 164080

Showing the first eight; more decompositions exist.
