Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39816, here are decompositions:
- 17 + 39799 = 39816
- 37 + 39779 = 39816
- 47 + 39769 = 39816
- 67 + 39749 = 39816
- 83 + 39733 = 39816
- 89 + 39727 = 39816
- 97 + 39719 = 39816
- 107 + 39709 = 39816
Showing the first eight; more decompositions exist.
