Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66764, here are decompositions:
- 13 + 66751 = 66764
- 31 + 66733 = 66764
- 43 + 66721 = 66764
- 67 + 66697 = 66764
- 163 + 66601 = 66764
- 193 + 66571 = 66764
- 211 + 66553 = 66764
- 223 + 66541 = 66764
Showing the first eight; more decompositions exist.
