Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11518, here are decompositions:
- 29 + 11489 = 11518
- 47 + 11471 = 11518
- 71 + 11447 = 11518
- 107 + 11411 = 11518
- 149 + 11369 = 11518
- 167 + 11351 = 11518
- 197 + 11321 = 11518
- 239 + 11279 = 11518
Showing the first eight; more decompositions exist.
