Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12668, here are decompositions:
- 31 + 12637 = 12668
- 67 + 12601 = 12668
- 79 + 12589 = 12668
- 127 + 12541 = 12668
- 151 + 12517 = 12668
- 157 + 12511 = 12668
- 181 + 12487 = 12668
- 211 + 12457 = 12668
Showing the first eight; more decompositions exist.
