Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528032, here are decompositions:
- 13 + 31528019 = 31528032
- 31 + 31528001 = 31528032
- 101 + 31527931 = 31528032
- 251 + 31527781 = 31528032
- 331 + 31527701 = 31528032
- 373 + 31527659 = 31528032
- 449 + 31527583 = 31528032
- 463 + 31527569 = 31528032
Showing the first eight; more decompositions exist.
