Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66918, here are decompositions:
- 29 + 66889 = 66918
- 41 + 66877 = 66918
- 67 + 66851 = 66918
- 97 + 66821 = 66918
- 109 + 66809 = 66918
- 127 + 66791 = 66918
- 167 + 66751 = 66918
- 179 + 66739 = 66918
Showing the first eight; more decompositions exist.
