Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544794, here are decompositions:
- 11 + 31544783 = 31544794
- 23 + 31544771 = 31544794
- 137 + 31544657 = 31544794
- 233 + 31544561 = 31544794
- 251 + 31544543 = 31544794
- 263 + 31544531 = 31544794
- 401 + 31544393 = 31544794
- 431 + 31544363 = 31544794
Showing the first eight; more decompositions exist.
