Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28162, here are decompositions:
- 11 + 28151 = 28162
- 53 + 28109 = 28162
- 131 + 28031 = 28162
- 179 + 27983 = 28162
- 269 + 27893 = 28162
- 311 + 27851 = 28162
- 353 + 27809 = 28162
- 359 + 27803 = 28162
Showing the first eight; more decompositions exist.
