Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66804, here are decompositions:
- 7 + 66797 = 66804
- 13 + 66791 = 66804
- 41 + 66763 = 66804
- 53 + 66751 = 66804
- 71 + 66733 = 66804
- 83 + 66721 = 66804
- 103 + 66701 = 66804
- 107 + 66697 = 66804
Showing the first eight; more decompositions exist.
