Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66836, here are decompositions:
- 73 + 66763 = 66836
- 97 + 66739 = 66836
- 103 + 66733 = 66836
- 139 + 66697 = 66836
- 193 + 66643 = 66836
- 283 + 66553 = 66836
- 307 + 66529 = 66836
- 313 + 66523 = 66836
Showing the first eight; more decompositions exist.
