Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67664, here are decompositions:
- 13 + 67651 = 67664
- 97 + 67567 = 67664
- 127 + 67537 = 67664
- 211 + 67453 = 67664
- 433 + 67231 = 67664
- 523 + 67141 = 67664
- 607 + 67057 = 67664
- 631 + 67033 = 67664
Showing the first eight; more decompositions exist.
