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.
