Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28146, here are decompositions:
- 23 + 28123 = 28146
- 37 + 28109 = 28146
- 47 + 28099 = 28146
- 59 + 28087 = 28146
- 89 + 28057 = 28146
- 127 + 28019 = 28146
- 149 + 27997 = 28146
- 163 + 27983 = 28146
Showing the first eight; more decompositions exist.
