Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87970, here are decompositions:

  • 11 + 87959 = 87970
  • 53 + 87917 = 87970
  • 59 + 87911 = 87970
  • 83 + 87887 = 87970
  • 89 + 87881 = 87970
  • 101 + 87869 = 87970
  • 137 + 87833 = 87970
  • 167 + 87803 = 87970

Showing the first eight; more decompositions exist.
