Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 21196, here are decompositions:

  • 3 + 21193 = 21196
  • 5 + 21191 = 21196
  • 17 + 21179 = 21196
  • 47 + 21149 = 21196
  • 53 + 21143 = 21196
  • 89 + 21107 = 21196
  • 107 + 21089 = 21196
  • 137 + 21059 = 21196

Showing the first eight; more decompositions exist.
