Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709186, here are decompositions:

  • 37 + 8709149 = 8709186
  • 47 + 8709139 = 8709186
  • 53 + 8709133 = 8709186
  • 107 + 8709079 = 8709186
  • 127 + 8709059 = 8709186
  • 179 + 8709007 = 8709186
  • 223 + 8708963 = 8709186
  • 293 + 8708893 = 8709186

Showing the first eight; more decompositions exist.
