Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20472, here are decompositions:
- 29 + 20443 = 20472
- 31 + 20441 = 20472
- 41 + 20431 = 20472
- 61 + 20411 = 20472
- 73 + 20399 = 20472
- 79 + 20393 = 20472
- 83 + 20389 = 20472
- 103 + 20369 = 20472
Showing the first eight; more decompositions exist.
