Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3814, here are decompositions:
- 11 + 3803 = 3814
- 17 + 3797 = 3814
- 47 + 3767 = 3814
- 53 + 3761 = 3814
- 113 + 3701 = 3814
- 137 + 3677 = 3814
- 191 + 3623 = 3814
- 197 + 3617 = 3814
Showing the first eight; more decompositions exist.
