Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16582, here are decompositions:
- 29 + 16553 = 16582
- 53 + 16529 = 16582
- 89 + 16493 = 16582
- 101 + 16481 = 16582
- 131 + 16451 = 16582
- 149 + 16433 = 16582
- 233 + 16349 = 16582
- 263 + 16319 = 16582
Showing the first eight; more decompositions exist.
