Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8711988, here are decompositions:

  • 17 + 8711971 = 8711988
  • 37 + 8711951 = 8711988
  • 67 + 8711921 = 8711988
  • 101 + 8711887 = 8711988
  • 137 + 8711851 = 8711988
  • 139 + 8711849 = 8711988
  • 167 + 8711821 = 8711988
  • 191 + 8711797 = 8711988

Showing the first eight; more decompositions exist.
