Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27220, here are decompositions:
- 23 + 27197 = 27220
- 29 + 27191 = 27220
- 41 + 27179 = 27220
- 113 + 27107 = 27220
- 227 + 26993 = 27220
- 233 + 26987 = 27220
- 239 + 26981 = 27220
- 269 + 26951 = 27220
Showing the first eight; more decompositions exist.
