Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12814, here are decompositions:
- 5 + 12809 = 12814
- 23 + 12791 = 12814
- 71 + 12743 = 12814
- 101 + 12713 = 12814
- 167 + 12647 = 12814
- 173 + 12641 = 12814
- 311 + 12503 = 12814
- 317 + 12497 = 12814
Showing the first eight; more decompositions exist.
