Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66846, here are decompositions:
- 5 + 66841 = 66846
- 37 + 66809 = 66846
- 83 + 66763 = 66846
- 97 + 66749 = 66846
- 107 + 66739 = 66846
- 113 + 66733 = 66846
- 149 + 66697 = 66846
- 163 + 66683 = 66846
Showing the first eight; more decompositions exist.
