Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64728, here are decompositions:
- 11 + 64717 = 64728
- 19 + 64709 = 64728
- 61 + 64667 = 64728
- 67 + 64661 = 64728
- 101 + 64627 = 64728
- 107 + 64621 = 64728
- 127 + 64601 = 64728
- 137 + 64591 = 64728
Showing the first eight; more decompositions exist.
