Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65398, here are decompositions:
- 5 + 65393 = 65398
- 17 + 65381 = 65398
- 41 + 65357 = 65398
- 71 + 65327 = 65398
- 89 + 65309 = 65398
- 131 + 65267 = 65398
- 227 + 65171 = 65398
- 251 + 65147 = 65398
Showing the first eight; more decompositions exist.
