Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 41664, here are decompositions:
- 5 + 41659 = 41664
- 13 + 41651 = 41664
- 17 + 41647 = 41664
- 23 + 41641 = 41664
- 37 + 41627 = 41664
- 43 + 41621 = 41664
- 47 + 41617 = 41664
- 53 + 41611 = 41664
Showing the first eight; more decompositions exist.
