Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66212, here are decompositions:
- 43 + 66169 = 66212
- 103 + 66109 = 66212
- 109 + 66103 = 66212
- 229 + 65983 = 66212
- 283 + 65929 = 66212
- 313 + 65899 = 66212
- 331 + 65881 = 66212
- 373 + 65839 = 66212
Showing the first eight; more decompositions exist.
