Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64740, here are decompositions:
- 23 + 64717 = 64740
- 31 + 64709 = 64740
- 47 + 64693 = 64740
- 61 + 64679 = 64740
- 73 + 64667 = 64740
- 79 + 64661 = 64740
- 107 + 64633 = 64740
- 113 + 64627 = 64740
Showing the first eight; more decompositions exist.
