Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12664, here are decompositions:
- 5 + 12659 = 12664
- 11 + 12653 = 12664
- 17 + 12647 = 12664
- 23 + 12641 = 12664
- 53 + 12611 = 12664
- 137 + 12527 = 12664
- 167 + 12497 = 12664
- 173 + 12491 = 12664
Showing the first eight; more decompositions exist.
