Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20452, here are decompositions:
- 11 + 20441 = 20452
- 41 + 20411 = 20452
- 53 + 20399 = 20452
- 59 + 20393 = 20452
- 83 + 20369 = 20452
- 191 + 20261 = 20452
- 233 + 20219 = 20452
- 251 + 20201 = 20452
Showing the first eight; more decompositions exist.
