Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533100, here are decompositions:
- 3 + 31533097 = 31533100
- 101 + 31532999 = 31533100
- 227 + 31532873 = 31533100
- 233 + 31532867 = 31533100
- 461 + 31532639 = 31533100
- 503 + 31532597 = 31533100
- 593 + 31532507 = 31533100
- 761 + 31532339 = 31533100
Showing the first eight; more decompositions exist.
