Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166548, here are decompositions:

7 + 166541 = 166548
61 + 166487 = 166548
131 + 166417 = 166548
139 + 166409 = 166548
149 + 166399 = 166548
191 + 166357 = 166548
197 + 166351 = 166548
199 + 166349 = 166548

Showing the first eight; more decompositions exist.
