Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80160, here are decompositions:

7 + 80153 = 80160
11 + 80149 = 80160
13 + 80147 = 80160
19 + 80141 = 80160
53 + 80107 = 80160
83 + 80077 = 80160
89 + 80071 = 80160
109 + 80051 = 80160

Showing the first eight; more decompositions exist.
