Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165674, here are decompositions:

7 + 165667 = 165674
73 + 165601 = 165674
151 + 165523 = 165674
163 + 165511 = 165674
211 + 165463 = 165674
277 + 165397 = 165674
283 + 165391 = 165674
307 + 165367 = 165674

Showing the first eight; more decompositions exist.
