Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64736, here are decompositions:
- 19 + 64717 = 64736
- 43 + 64693 = 64736
- 73 + 64663 = 64736
- 103 + 64633 = 64736
- 109 + 64627 = 64736
- 127 + 64609 = 64736
- 157 + 64579 = 64736
- 223 + 64513 = 64736
Showing the first eight; more decompositions exist.
