Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11718, here are decompositions:
- 17 + 11701 = 11718
- 19 + 11699 = 11718
- 29 + 11689 = 11718
- 37 + 11681 = 11718
- 41 + 11677 = 11718
- 61 + 11657 = 11718
- 97 + 11621 = 11718
- 101 + 11617 = 11718
Showing the first eight; more decompositions exist.
