Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530928, here are decompositions:
- 101 + 31530827 = 31530928
- 131 + 31530797 = 31530928
- 227 + 31530701 = 31530928
- 269 + 31530659 = 31530928
- 311 + 31530617 = 31530928
- 431 + 31530497 = 31530928
- 449 + 31530479 = 31530928
- 491 + 31530437 = 31530928
Showing the first eight; more decompositions exist.
