Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12848, here are decompositions:
- 7 + 12841 = 12848
- 19 + 12829 = 12848
- 67 + 12781 = 12848
- 109 + 12739 = 12848
- 127 + 12721 = 12848
- 151 + 12697 = 12848
- 211 + 12637 = 12848
- 229 + 12619 = 12848
Showing the first eight; more decompositions exist.
