Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66866, here are decompositions:
- 3 + 66863 = 66866
- 13 + 66853 = 66866
- 103 + 66763 = 66866
- 127 + 66739 = 66866
- 223 + 66643 = 66866
- 313 + 66553 = 66866
- 337 + 66529 = 66866
- 367 + 66499 = 66866
Showing the first eight; more decompositions exist.
