Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11380, here are decompositions:

  • 11 + 11369 = 11380
  • 29 + 11351 = 11380
  • 59 + 11321 = 11380
  • 101 + 11279 = 11380
  • 107 + 11273 = 11380
  • 137 + 11243 = 11380
  • 167 + 11213 = 11380
  • 263 + 11117 = 11380

Showing the first eight; more decompositions exist.
