Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 814, here are decompositions:
- 3 + 811 = 814
- 5 + 809 = 814
- 17 + 797 = 814
- 41 + 773 = 814
- 53 + 761 = 814
- 71 + 743 = 814
- 113 + 701 = 814
- 131 + 683 = 814
Showing the first eight; more decompositions exist.
