Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65428, here are decompositions:
- 5 + 65423 = 65428
- 47 + 65381 = 65428
- 71 + 65357 = 65428
- 101 + 65327 = 65428
- 257 + 65171 = 65428
- 281 + 65147 = 65428
- 317 + 65111 = 65428
- 401 + 65027 = 65428
Showing the first eight; more decompositions exist.
