Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544, here are decompositions:
- 3 + 31541 = 31544
- 13 + 31531 = 31544
- 31 + 31513 = 31544
- 67 + 31477 = 31544
- 151 + 31393 = 31544
- 157 + 31387 = 31544
- 211 + 31333 = 31544
- 223 + 31321 = 31544
Showing the first eight; more decompositions exist.
