Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166126, here are decompositions:

83 + 166043 = 166126
113 + 166013 = 166126
179 + 165947 = 166126
239 + 165887 = 166126
269 + 165857 = 166126
293 + 165833 = 166126
347 + 165779 = 166126
419 + 165707 = 166126

Showing the first eight; more decompositions exist.
