Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28200, here are decompositions:
- 17 + 28183 = 28200
- 19 + 28181 = 28200
- 37 + 28163 = 28200
- 89 + 28111 = 28200
- 101 + 28099 = 28200
- 103 + 28097 = 28200
- 113 + 28087 = 28200
- 131 + 28069 = 28200
Showing the first eight; more decompositions exist.
