Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531022, here are decompositions:
- 43 + 31530979 = 31531022
- 79 + 31530943 = 31531022
- 181 + 31530841 = 31531022
- 223 + 31530799 = 31531022
- 373 + 31530649 = 31531022
- 379 + 31530643 = 31531022
- 433 + 31530589 = 31531022
- 499 + 31530523 = 31531022
Showing the first eight; more decompositions exist.
