Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530904, here are decompositions:
- 3 + 31530901 = 31530904
- 11 + 31530893 = 31530904
- 71 + 31530833 = 31530904
- 107 + 31530797 = 31530904
- 131 + 31530773 = 31530904
- 191 + 31530713 = 31530904
- 263 + 31530641 = 31530904
- 311 + 31530593 = 31530904
Showing the first eight; more decompositions exist.
