Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28174, here are decompositions:
- 11 + 28163 = 28174
- 23 + 28151 = 28174
- 173 + 28001 = 28174
- 191 + 27983 = 28174
- 227 + 27947 = 28174
- 233 + 27941 = 28174
- 257 + 27917 = 28174
- 281 + 27893 = 28174
Showing the first eight; more decompositions exist.
