Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3848, here are decompositions:
- 79 + 3769 = 3848
- 109 + 3739 = 3848
- 139 + 3709 = 3848
- 151 + 3697 = 3848
- 157 + 3691 = 3848
- 211 + 3637 = 3848
- 241 + 3607 = 3848
- 277 + 3571 = 3848
Showing the first eight; more decompositions exist.
