Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526558, here are decompositions:
- 31 + 31526527 = 31526558
- 61 + 31526497 = 31526558
- 127 + 31526431 = 31526558
- 139 + 31526419 = 31526558
- 199 + 31526359 = 31526558
- 241 + 31526317 = 31526558
- 277 + 31526281 = 31526558
- 331 + 31526227 = 31526558
Showing the first eight; more decompositions exist.
