Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11660, here are decompositions:
- 3 + 11657 = 11660
- 43 + 11617 = 11660
- 67 + 11593 = 11660
- 73 + 11587 = 11660
- 109 + 11551 = 11660
- 157 + 11503 = 11660
- 163 + 11497 = 11660
- 193 + 11467 = 11660
Showing the first eight; more decompositions exist.
