Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20626, here are decompositions:
- 83 + 20543 = 20626
- 149 + 20477 = 20626
- 227 + 20399 = 20626
- 233 + 20393 = 20626
- 257 + 20369 = 20626
- 269 + 20357 = 20626
- 293 + 20333 = 20626
- 443 + 20183 = 20626
Showing the first eight; more decompositions exist.
