Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707986, here are decompositions:

  • 17 + 8707969 = 8707986
  • 47 + 8707939 = 8707986
  • 83 + 8707903 = 8707986
  • 103 + 8707883 = 8707986
  • 107 + 8707879 = 8707986
  • 109 + 8707877 = 8707986
  • 113 + 8707873 = 8707986
  • 149 + 8707837 = 8707986

Showing the first eight; more decompositions exist.
