Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28132, here are decompositions:
- 23 + 28109 = 28132
- 101 + 28031 = 28132
- 113 + 28019 = 28132
- 131 + 28001 = 28132
- 149 + 27983 = 28132
- 179 + 27953 = 28132
- 191 + 27941 = 28132
- 239 + 27893 = 28132
Showing the first eight; more decompositions exist.
