Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530796, here are decompositions:
- 23 + 31530773 = 31530796
- 83 + 31530713 = 31530796
- 113 + 31530683 = 31530796
- 137 + 31530659 = 31530796
- 179 + 31530617 = 31530796
- 317 + 31530479 = 31530796
- 359 + 31530437 = 31530796
- 419 + 31530377 = 31530796
Showing the first eight; more decompositions exist.
