Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39744, here are decompositions:
- 11 + 39733 = 39744
- 17 + 39727 = 39744
- 41 + 39703 = 39744
- 73 + 39671 = 39744
- 113 + 39631 = 39744
- 137 + 39607 = 39744
- 163 + 39581 = 39744
- 181 + 39563 = 39744
Showing the first eight; more decompositions exist.
