Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31444, here are decompositions:
- 47 + 31397 = 31444
- 53 + 31391 = 31444
- 107 + 31337 = 31444
- 137 + 31307 = 31444
- 167 + 31277 = 31444
- 173 + 31271 = 31444
- 191 + 31253 = 31444
- 197 + 31247 = 31444
Showing the first eight; more decompositions exist.
