Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528546, here are decompositions:
- 47 + 31528499 = 31528546
- 113 + 31528433 = 31528546
- 173 + 31528373 = 31528546
- 197 + 31528349 = 31528546
- 233 + 31528313 = 31528546
- 263 + 31528283 = 31528546
- 317 + 31528229 = 31528546
- 389 + 31528157 = 31528546
Showing the first eight; more decompositions exist.
