Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8711200, here are decompositions:

  • 11 + 8711189 = 8711200
  • 41 + 8711159 = 8711200
  • 59 + 8711141 = 8711200
  • 83 + 8711117 = 8711200
  • 149 + 8711051 = 8711200
  • 167 + 8711033 = 8711200
  • 191 + 8711009 = 8711200
  • 227 + 8710973 = 8711200

Showing the first eight; more decompositions exist.
