Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11664, here are decompositions:
- 7 + 11657 = 11664
- 31 + 11633 = 11664
- 43 + 11621 = 11664
- 47 + 11617 = 11664
- 67 + 11597 = 11664
- 71 + 11593 = 11664
- 113 + 11551 = 11664
- 137 + 11527 = 11664
Showing the first eight; more decompositions exist.
