Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166748, here are decompositions:

7 + 166741 = 166748
79 + 166669 = 166748
139 + 166609 = 166748
151 + 166597 = 166748
181 + 166567 = 166748
277 + 166471 = 166748
331 + 166417 = 166748
349 + 166399 = 166748

Showing the first eight; more decompositions exist.
