Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528354, here are decompositions:
- 5 + 31528349 = 31528354
- 17 + 31528337 = 31528354
- 41 + 31528313 = 31528354
- 71 + 31528283 = 31528354
- 113 + 31528241 = 31528354
- 197 + 31528157 = 31528354
- 227 + 31528127 = 31528354
- 233 + 31528121 = 31528354
Showing the first eight; more decompositions exist.
