Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 32128, here are decompositions:
- 11 + 32117 = 32128
- 29 + 32099 = 32128
- 59 + 32069 = 32128
- 71 + 32057 = 32128
- 101 + 32027 = 32128
- 137 + 31991 = 32128
- 269 + 31859 = 32128
- 281 + 31847 = 32128
Showing the first eight; more decompositions exist.
