Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28234, here are decompositions:
- 5 + 28229 = 28234
- 23 + 28211 = 28234
- 53 + 28181 = 28234
- 71 + 28163 = 28234
- 83 + 28151 = 28234
- 137 + 28097 = 28234
- 233 + 28001 = 28234
- 251 + 27983 = 28234
Showing the first eight; more decompositions exist.
