Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530820, here are decompositions:
- 23 + 31530797 = 31530820
- 47 + 31530773 = 31530820
- 107 + 31530713 = 31530820
- 137 + 31530683 = 31530820
- 179 + 31530641 = 31530820
- 227 + 31530593 = 31530820
- 383 + 31530437 = 31530820
- 401 + 31530419 = 31530820
Showing the first eight; more decompositions exist.
