Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66308, here are decompositions:
- 7 + 66301 = 66308
- 37 + 66271 = 66308
- 139 + 66169 = 66308
- 199 + 66109 = 66308
- 241 + 66067 = 66308
- 271 + 66037 = 66308
- 379 + 65929 = 66308
- 409 + 65899 = 66308
Showing the first eight; more decompositions exist.
