Goldbach decomposition

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.
