Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28150, here are decompositions:
- 41 + 28109 = 28150
- 53 + 28097 = 28150
- 131 + 28019 = 28150
- 149 + 28001 = 28150
- 167 + 27983 = 28150
- 197 + 27953 = 28150
- 233 + 27917 = 28150
- 257 + 27893 = 28150
Showing the first eight; more decompositions exist.
