Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82540, here are decompositions:
- 11 + 82529 = 82540
- 41 + 82499 = 82540
- 47 + 82493 = 82540
- 53 + 82487 = 82540
- 71 + 82469 = 82540
- 83 + 82457 = 82540
- 167 + 82373 = 82540
- 179 + 82361 = 82540
Showing the first eight; more decompositions exist.
