Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28674, here are decompositions:
- 5 + 28669 = 28674
- 11 + 28663 = 28674
- 13 + 28661 = 28674
- 17 + 28657 = 28674
- 31 + 28643 = 28674
- 43 + 28631 = 28674
- 47 + 28627 = 28674
- 53 + 28621 = 28674
Showing the first eight; more decompositions exist.
