Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 63880, here are decompositions:
- 17 + 63863 = 63880
- 23 + 63857 = 63880
- 41 + 63839 = 63880
- 71 + 63809 = 63880
- 107 + 63773 = 63880
- 137 + 63743 = 63880
- 191 + 63689 = 63880
- 233 + 63647 = 63880
Showing the first eight; more decompositions exist.
