Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533028, here are decompositions:
- 29 + 31532999 = 31533028
- 47 + 31532981 = 31533028
- 89 + 31532939 = 31533028
- 251 + 31532777 = 31533028
- 389 + 31532639 = 31533028
- 431 + 31532597 = 31533028
- 521 + 31532507 = 31533028
- 599 + 31532429 = 31533028
Showing the first eight; more decompositions exist.
