Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43666, here are decompositions:

5 + 43661 = 43666
17 + 43649 = 43666
53 + 43613 = 43666
59 + 43607 = 43666
89 + 43577 = 43666
149 + 43517 = 43666
167 + 43499 = 43666
179 + 43487 = 43666

Showing the first eight; more decompositions exist.
