Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28892, here are decompositions:
- 13 + 28879 = 28892
- 79 + 28813 = 28892
- 103 + 28789 = 28892
- 139 + 28753 = 28892
- 163 + 28729 = 28892
- 181 + 28711 = 28892
- 223 + 28669 = 28892
- 229 + 28663 = 28892
Showing the first eight; more decompositions exist.
