Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66740, here are decompositions:

7 + 66733 = 66740
19 + 66721 = 66740
43 + 66697 = 66740
97 + 66643 = 66740
139 + 66601 = 66740
199 + 66541 = 66740
211 + 66529 = 66740
241 + 66499 = 66740

Showing the first eight; more decompositions exist.
