Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64178, here are decompositions:
- 7 + 64171 = 64178
- 97 + 64081 = 64178
- 181 + 63997 = 64178
- 229 + 63949 = 64178
- 271 + 63907 = 64178
- 277 + 63901 = 64178
- 337 + 63841 = 64178
- 379 + 63799 = 64178
Showing the first eight; more decompositions exist.
