Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66750, here are decompositions:
- 11 + 66739 = 66750
- 17 + 66733 = 66750
- 29 + 66721 = 66750
- 37 + 66713 = 66750
- 53 + 66697 = 66750
- 67 + 66683 = 66750
- 97 + 66653 = 66750
- 107 + 66643 = 66750
Showing the first eight; more decompositions exist.
