Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528432, here are decompositions:
- 59 + 31528373 = 31528432
- 83 + 31528349 = 31528432
- 149 + 31528283 = 31528432
- 191 + 31528241 = 31528432
- 263 + 31528169 = 31528432
- 281 + 31528151 = 31528432
- 311 + 31528121 = 31528432
- 431 + 31528001 = 31528432
Showing the first eight; more decompositions exist.
