Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11666, here are decompositions:
- 73 + 11593 = 11666
- 79 + 11587 = 11666
- 139 + 11527 = 11666
- 163 + 11503 = 11666
- 199 + 11467 = 11666
- 223 + 11443 = 11666
- 229 + 11437 = 11666
- 283 + 11383 = 11666
Showing the first eight; more decompositions exist.
