Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82856, here are decompositions:
- 19 + 82837 = 82856
- 43 + 82813 = 82856
- 97 + 82759 = 82856
- 127 + 82729 = 82856
- 157 + 82699 = 82856
- 199 + 82657 = 82856
- 223 + 82633 = 82856
- 307 + 82549 = 82856
Showing the first eight; more decompositions exist.
