Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526250, here are decompositions:
- 11 + 31526239 = 31526250
- 23 + 31526227 = 31526250
- 29 + 31526221 = 31526250
- 37 + 31526213 = 31526250
- 43 + 31526207 = 31526250
- 53 + 31526197 = 31526250
- 59 + 31526191 = 31526250
- 61 + 31526189 = 31526250
Showing the first eight; more decompositions exist.
