Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 41666, here are decompositions:

7 + 41659 = 41666
19 + 41647 = 41666
73 + 41593 = 41666
127 + 41539 = 41666
199 + 41467 = 41666
223 + 41443 = 41666
277 + 41389 = 41666
367 + 41299 = 41666

Showing the first eight; more decompositions exist.
