Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66718, here are decompositions:
- 5 + 66713 = 66718
- 17 + 66701 = 66718
- 89 + 66629 = 66718
- 101 + 66617 = 66718
- 131 + 66587 = 66718
- 149 + 66569 = 66718
- 227 + 66491 = 66718
- 251 + 66467 = 66718
Showing the first eight; more decompositions exist.
