Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66722, here are decompositions:
- 79 + 66643 = 66722
- 151 + 66571 = 66722
- 181 + 66541 = 66722
- 193 + 66529 = 66722
- 199 + 66523 = 66722
- 223 + 66499 = 66722
- 349 + 66373 = 66722
- 379 + 66343 = 66722
Showing the first eight; more decompositions exist.
