Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28672, here are decompositions:
- 3 + 28669 = 28672
- 11 + 28661 = 28672
- 23 + 28649 = 28672
- 29 + 28643 = 28672
- 41 + 28631 = 28672
- 53 + 28619 = 28672
- 101 + 28571 = 28672
- 113 + 28559 = 28672
Showing the first eight; more decompositions exist.
