Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526310, here are decompositions:
- 29 + 31526281 = 31526310
- 37 + 31526273 = 31526310
- 71 + 31526239 = 31526310
- 83 + 31526227 = 31526310
- 89 + 31526221 = 31526310
- 97 + 31526213 = 31526310
- 103 + 31526207 = 31526310
- 113 + 31526197 = 31526310
Showing the first eight; more decompositions exist.
