Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66768, here are decompositions:
- 5 + 66763 = 66768
- 17 + 66751 = 66768
- 19 + 66749 = 66768
- 29 + 66739 = 66768
- 47 + 66721 = 66768
- 67 + 66701 = 66768
- 71 + 66697 = 66768
- 139 + 66629 = 66768
Showing the first eight; more decompositions exist.
