Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28976, here are decompositions:
- 43 + 28933 = 28976
- 67 + 28909 = 28976
- 97 + 28879 = 28976
- 109 + 28867 = 28976
- 139 + 28837 = 28976
- 163 + 28813 = 28976
- 223 + 28753 = 28976
- 307 + 28669 = 28976
Showing the first eight; more decompositions exist.
