Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530868, here are decompositions:
- 41 + 31530827 = 31530868
- 71 + 31530797 = 31530868
- 167 + 31530701 = 31530868
- 227 + 31530641 = 31530868
- 251 + 31530617 = 31530868
- 389 + 31530479 = 31530868
- 431 + 31530437 = 31530868
- 449 + 31530419 = 31530868
Showing the first eight; more decompositions exist.
