Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82686, here are decompositions:
- 29 + 82657 = 82686
- 53 + 82633 = 82686
- 67 + 82619 = 82686
- 73 + 82613 = 82686
- 127 + 82559 = 82686
- 137 + 82549 = 82686
- 157 + 82529 = 82686
- 179 + 82507 = 82686
Showing the first eight; more decompositions exist.
