Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82438, here are decompositions:
- 17 + 82421 = 82438
- 89 + 82349 = 82438
- 131 + 82307 = 82438
- 137 + 82301 = 82438
- 197 + 82241 = 82438
- 401 + 82037 = 82438
- 431 + 82007 = 82438
- 467 + 81971 = 82438
Showing the first eight; more decompositions exist.
