Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11684, here are decompositions:
- 3 + 11681 = 11684
- 7 + 11677 = 11684
- 67 + 11617 = 11684
- 97 + 11587 = 11684
- 157 + 11527 = 11684
- 181 + 11503 = 11684
- 193 + 11491 = 11684
- 241 + 11443 = 11684
Showing the first eight; more decompositions exist.
