Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 21060, here are decompositions:
- 29 + 21031 = 21060
- 37 + 21023 = 21060
- 41 + 21019 = 21060
- 43 + 21017 = 21060
- 47 + 21013 = 21060
- 59 + 21001 = 21060
- 79 + 20981 = 21060
- 97 + 20963 = 21060
Showing the first eight; more decompositions exist.
