Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528102, here are decompositions:
- 83 + 31528019 = 31528102
- 101 + 31528001 = 31528102
- 401 + 31527701 = 31528102
- 443 + 31527659 = 31528102
- 569 + 31527533 = 31528102
- 911 + 31527191 = 31528102
- 929 + 31527173 = 31528102
- 953 + 31527149 = 31528102
Showing the first eight; more decompositions exist.
