Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166184, here are decompositions:

37 + 166147 = 166184
103 + 166081 = 166184
157 + 166027 = 166184
163 + 166021 = 166184
223 + 165961 = 166184
283 + 165901 = 166184
307 + 165877 = 166184
367 + 165817 = 166184

Showing the first eight; more decompositions exist.
