Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531028, here are decompositions:
- 127 + 31530901 = 31531028
- 229 + 31530799 = 31531028
- 349 + 31530679 = 31531028
- 367 + 31530661 = 31531028
- 379 + 31530649 = 31531028
- 421 + 31530607 = 31531028
- 439 + 31530589 = 31531028
- 457 + 31530571 = 31531028
Showing the first eight; more decompositions exist.
