Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66186, here are decompositions:

  • 7 + 66179 = 66186
  • 13 + 66173 = 66186
  • 17 + 66169 = 66186
  • 79 + 66107 = 66186
  • 83 + 66103 = 66186
  • 97 + 66089 = 66186
  • 103 + 66083 = 66186
  • 139 + 66047 = 66186

Showing the first eight; more decompositions exist.
