Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531734, here are decompositions:
- 7 + 31531727 = 31531734
- 67 + 31531667 = 31531734
- 107 + 31531627 = 31531734
- 211 + 31531523 = 31531734
- 251 + 31531483 = 31531734
- 263 + 31531471 = 31531734
- 277 + 31531457 = 31531734
- 281 + 31531453 = 31531734
Showing the first eight; more decompositions exist.
