Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528720, here are decompositions:
- 23 + 31528697 = 31528720
- 107 + 31528613 = 31528720
- 173 + 31528547 = 31528720
- 269 + 31528451 = 31528720
- 347 + 31528373 = 31528720
- 383 + 31528337 = 31528720
- 479 + 31528241 = 31528720
- 491 + 31528229 = 31528720
Showing the first eight; more decompositions exist.
