Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28662, here are decompositions:
- 5 + 28657 = 28662
- 13 + 28649 = 28662
- 19 + 28643 = 28662
- 31 + 28631 = 28662
- 41 + 28621 = 28662
- 43 + 28619 = 28662
- 59 + 28603 = 28662
- 71 + 28591 = 28662
Showing the first eight; more decompositions exist.
