Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82518, here are decompositions:
- 11 + 82507 = 82518
- 19 + 82499 = 82518
- 31 + 82487 = 82518
- 47 + 82471 = 82518
- 61 + 82457 = 82518
- 97 + 82421 = 82518
- 131 + 82387 = 82518
- 157 + 82361 = 82518
Showing the first eight; more decompositions exist.
