Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66902, here are decompositions:
- 13 + 66889 = 66902
- 19 + 66883 = 66902
- 61 + 66841 = 66902
- 139 + 66763 = 66902
- 151 + 66751 = 66902
- 163 + 66739 = 66902
- 181 + 66721 = 66902
- 331 + 66571 = 66902
Showing the first eight; more decompositions exist.
