Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71456, here are decompositions:
- 3 + 71453 = 71456
- 13 + 71443 = 71456
- 19 + 71437 = 71456
- 37 + 71419 = 71456
- 43 + 71413 = 71456
- 67 + 71389 = 71456
- 97 + 71359 = 71456
- 103 + 71353 = 71456
Showing the first eight; more decompositions exist.
