Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532310, here are decompositions:
- 31 + 31532279 = 31532310
- 41 + 31532269 = 31532310
- 83 + 31532227 = 31532310
- 101 + 31532209 = 31532310
- 107 + 31532203 = 31532310
- 193 + 31532117 = 31532310
- 197 + 31532113 = 31532310
- 239 + 31532071 = 31532310
Showing the first eight; more decompositions exist.
