Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28760, here are decompositions:
- 7 + 28753 = 28760
- 31 + 28729 = 28760
- 37 + 28723 = 28760
- 73 + 28687 = 28760
- 97 + 28663 = 28760
- 103 + 28657 = 28760
- 139 + 28621 = 28760
- 157 + 28603 = 28760
Showing the first eight; more decompositions exist.
