Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64904, here are decompositions:
- 3 + 64901 = 64904
- 13 + 64891 = 64904
- 157 + 64747 = 64904
- 211 + 64693 = 64904
- 241 + 64663 = 64904
- 271 + 64633 = 64904
- 277 + 64627 = 64904
- 283 + 64621 = 64904
Showing the first eight; more decompositions exist.
