Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66822, here are decompositions:
- 13 + 66809 = 66822
- 31 + 66791 = 66822
- 59 + 66763 = 66822
- 71 + 66751 = 66822
- 73 + 66749 = 66822
- 83 + 66739 = 66822
- 89 + 66733 = 66822
- 101 + 66721 = 66822
Showing the first eight; more decompositions exist.
