Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87966, here are decompositions:

  • 5 + 87961 = 87966
  • 7 + 87959 = 87966
  • 23 + 87943 = 87966
  • 79 + 87887 = 87966
  • 89 + 87877 = 87966
  • 97 + 87869 = 87966
  • 113 + 87853 = 87966
  • 163 + 87803 = 87966

Showing the first eight; more decompositions exist.
