Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534000, here are decompositions:
- 41 + 31533959 = 31534000
- 89 + 31533911 = 31534000
- 167 + 31533833 = 31534000
- 227 + 31533773 = 31534000
- 293 + 31533707 = 31534000
- 359 + 31533641 = 31534000
- 389 + 31533611 = 31534000
- 401 + 31533599 = 31534000
Showing the first eight; more decompositions exist.
