Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78660, here are decompositions:
- 7 + 78653 = 78660
- 11 + 78649 = 78660
- 17 + 78643 = 78660
- 37 + 78623 = 78660
- 53 + 78607 = 78660
- 67 + 78593 = 78660
- 83 + 78577 = 78660
- 89 + 78571 = 78660
Showing the first eight; more decompositions exist.
