Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57640, here are decompositions:
- 3 + 57637 = 57640
- 47 + 57593 = 57640
- 53 + 57587 = 57640
- 83 + 57557 = 57640
- 113 + 57527 = 57640
- 137 + 57503 = 57640
- 173 + 57467 = 57640
- 227 + 57413 = 57640
Showing the first eight; more decompositions exist.
