Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66788, here are decompositions:
- 37 + 66751 = 66788
- 67 + 66721 = 66788
- 331 + 66457 = 66788
- 487 + 66301 = 66788
- 619 + 66169 = 66788
- 751 + 66037 = 66788
- 859 + 65929 = 66788
- 907 + 65881 = 66788
Showing the first eight; more decompositions exist.
