Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39648, here are decompositions:
- 17 + 39631 = 39648
- 29 + 39619 = 39648
- 41 + 39607 = 39648
- 67 + 39581 = 39648
- 79 + 39569 = 39648
- 97 + 39551 = 39648
- 107 + 39541 = 39648
- 127 + 39521 = 39648
Showing the first eight; more decompositions exist.
