Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28788, here are decompositions:
- 17 + 28771 = 28788
- 29 + 28759 = 28788
- 37 + 28751 = 28788
- 59 + 28729 = 28788
- 101 + 28687 = 28788
- 127 + 28661 = 28788
- 131 + 28657 = 28788
- 139 + 28649 = 28788
Showing the first eight; more decompositions exist.
