Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542434, here are decompositions:
- 37 + 31542397 = 31542434
- 43 + 31542391 = 31542434
- 61 + 31542373 = 31542434
- 271 + 31542163 = 31542434
- 331 + 31542103 = 31542434
- 367 + 31542067 = 31542434
- 397 + 31542037 = 31542434
- 421 + 31542013 = 31542434
Showing the first eight; more decompositions exist.
