Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8711290, here are decompositions:

  • 23 + 8711267 = 8711290
  • 53 + 8711237 = 8711290
  • 101 + 8711189 = 8711290
  • 131 + 8711159 = 8711290
  • 149 + 8711141 = 8711290
  • 173 + 8711117 = 8711290
  • 239 + 8711051 = 8711290
  • 257 + 8711033 = 8711290

Showing the first eight; more decompositions exist.
