Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42790, here are decompositions:
- 3 + 42787 = 42790
- 17 + 42773 = 42790
- 23 + 42767 = 42790
- 47 + 42743 = 42790
- 53 + 42737 = 42790
- 71 + 42719 = 42790
- 89 + 42701 = 42790
- 101 + 42689 = 42790
Showing the first eight; more decompositions exist.
