Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66726, here are decompositions:
- 5 + 66721 = 66726
- 13 + 66713 = 66726
- 29 + 66697 = 66726
- 43 + 66683 = 66726
- 73 + 66653 = 66726
- 83 + 66643 = 66726
- 97 + 66629 = 66726
- 109 + 66617 = 66726
Showing the first eight; more decompositions exist.
