Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 168120, here are decompositions:

11 + 168109 = 168120
31 + 168089 = 168120
37 + 168083 = 168120
53 + 168067 = 168120
83 + 168037 = 168120
97 + 168023 = 168120
107 + 168013 = 168120
149 + 167971 = 168120

Showing the first eight; more decompositions exist.
