Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 169080, here are decompositions:

11 + 169069 = 169080
13 + 169067 = 169080
17 + 169063 = 169080
31 + 169049 = 169080
61 + 169019 = 169080
71 + 169009 = 169080
73 + 169007 = 169080
89 + 168991 = 169080

Showing the first eight; more decompositions exist.
