Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7814, here are decompositions:
- 61 + 7753 = 7814
- 73 + 7741 = 7814
- 97 + 7717 = 7814
- 127 + 7687 = 7814
- 193 + 7621 = 7814
- 211 + 7603 = 7814
- 223 + 7591 = 7814
- 241 + 7573 = 7814
Showing the first eight; more decompositions exist.
