Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6814, here are decompositions:
- 11 + 6803 = 6814
- 23 + 6791 = 6814
- 53 + 6761 = 6814
- 113 + 6701 = 6814
- 233 + 6581 = 6814
- 251 + 6563 = 6814
- 263 + 6551 = 6814
- 293 + 6521 = 6814
Showing the first eight; more decompositions exist.
