Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11180, here are decompositions:

  • 3 + 11177 = 11180
  • 7 + 11173 = 11180
  • 19 + 11161 = 11180
  • 31 + 11149 = 11180
  • 61 + 11119 = 11180
  • 67 + 11113 = 11180
  • 97 + 11083 = 11180
  • 109 + 11071 = 11180

Showing the first eight; more decompositions exist.
