Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42666, here are decompositions:

17 + 42649 = 42666
23 + 42643 = 42666
89 + 42577 = 42666
97 + 42569 = 42666
109 + 42557 = 42666
157 + 42509 = 42666
167 + 42499 = 42666
179 + 42487 = 42666

Showing the first eight; more decompositions exist.
