Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166088, here are decompositions:

7 + 166081 = 166088
61 + 166027 = 166088
67 + 166021 = 166088
127 + 165961 = 166088
157 + 165931 = 166088
211 + 165877 = 166088
271 + 165817 = 166088
277 + 165811 = 166088

Showing the first eight; more decompositions exist.
