Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166274, here are decompositions:

37 + 166237 = 166274
67 + 166207 = 166274
127 + 166147 = 166274
193 + 166081 = 166274
211 + 166063 = 166274
313 + 165961 = 166274
373 + 165901 = 166274
397 + 165877 = 166274

Showing the first eight; more decompositions exist.
