Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66378, here are decompositions:
- 5 + 66373 = 66378
- 17 + 66361 = 66378
- 19 + 66359 = 66378
- 31 + 66347 = 66378
- 41 + 66337 = 66378
- 107 + 66271 = 66378
- 139 + 66239 = 66378
- 157 + 66221 = 66378
Showing the first eight; more decompositions exist.
