Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528372, here are decompositions:
- 23 + 31528349 = 31528372
- 59 + 31528313 = 31528372
- 89 + 31528283 = 31528372
- 131 + 31528241 = 31528372
- 251 + 31528121 = 31528372
- 269 + 31528103 = 31528372
- 353 + 31528019 = 31528372
- 431 + 31527941 = 31528372
Showing the first eight; more decompositions exist.
