Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545836, here are decompositions:
- 73 + 31545763 = 31545836
- 97 + 31545739 = 31545836
- 229 + 31545607 = 31545836
- 337 + 31545499 = 31545836
- 349 + 31545487 = 31545836
- 367 + 31545469 = 31545836
- 397 + 31545439 = 31545836
- 457 + 31545379 = 31545836
Showing the first eight; more decompositions exist.
