Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82666, here are decompositions:
- 47 + 82619 = 82666
- 53 + 82613 = 82666
- 107 + 82559 = 82666
- 137 + 82529 = 82666
- 167 + 82499 = 82666
- 173 + 82493 = 82666
- 179 + 82487 = 82666
- 197 + 82469 = 82666
Showing the first eight; more decompositions exist.
