Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82516, here are decompositions:
- 17 + 82499 = 82516
- 23 + 82493 = 82516
- 29 + 82487 = 82516
- 47 + 82469 = 82516
- 53 + 82463 = 82516
- 59 + 82457 = 82516
- 167 + 82349 = 82516
- 293 + 82223 = 82516
Showing the first eight; more decompositions exist.
