Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166002, here are decompositions:

19 + 165983 = 166002
41 + 165961 = 166002
61 + 165941 = 166002
71 + 165931 = 166002
101 + 165901 = 166002
173 + 165829 = 166002
191 + 165811 = 166002
223 + 165779 = 166002

Showing the first eight; more decompositions exist.
