Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66790, here are decompositions:
- 41 + 66749 = 66790
- 89 + 66701 = 66790
- 107 + 66683 = 66790
- 137 + 66653 = 66790
- 173 + 66617 = 66790
- 197 + 66593 = 66790
- 257 + 66533 = 66790
- 281 + 66509 = 66790
Showing the first eight; more decompositions exist.
