Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166844, here are decompositions:

3 + 166841 = 166844
37 + 166807 = 166844
61 + 166783 = 166844
103 + 166741 = 166844
151 + 166693 = 166844
241 + 166603 = 166844
277 + 166567 = 166844
283 + 166561 = 166844

Showing the first eight; more decompositions exist.
