Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12648, here are decompositions:
- 7 + 12641 = 12648
- 11 + 12637 = 12648
- 29 + 12619 = 12648
- 37 + 12611 = 12648
- 47 + 12601 = 12648
- 59 + 12589 = 12648
- 71 + 12577 = 12648
- 79 + 12569 = 12648
Showing the first eight; more decompositions exist.
