Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66746, here are decompositions:
- 7 + 66739 = 66746
- 13 + 66733 = 66746
- 103 + 66643 = 66746
- 193 + 66553 = 66746
- 223 + 66523 = 66746
- 283 + 66463 = 66746
- 373 + 66373 = 66746
- 409 + 66337 = 66746
Showing the first eight; more decompositions exist.
