Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86970, here are decompositions:

  • 11 + 86959 = 86970
  • 19 + 86951 = 86970
  • 31 + 86939 = 86970
  • 41 + 86929 = 86970
  • 43 + 86927 = 86970
  • 47 + 86923 = 86970
  • 101 + 86869 = 86970
  • 109 + 86861 = 86970

Showing the first eight; more decompositions exist.
