Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 48640, here are decompositions:
- 17 + 48623 = 48640
- 29 + 48611 = 48640
- 47 + 48593 = 48640
- 101 + 48539 = 48640
- 107 + 48533 = 48640
- 113 + 48527 = 48640
- 149 + 48491 = 48640
- 167 + 48473 = 48640
Showing the first eight; more decompositions exist.
