Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11668, here are decompositions:
- 11 + 11657 = 11668
- 47 + 11621 = 11668
- 71 + 11597 = 11668
- 89 + 11579 = 11668
- 149 + 11519 = 11668
- 179 + 11489 = 11668
- 197 + 11471 = 11668
- 257 + 11411 = 11668
Showing the first eight; more decompositions exist.
