Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707980, here are decompositions:

  • 11 + 8707969 = 8707980
  • 41 + 8707939 = 8707980
  • 97 + 8707883 = 8707980
  • 101 + 8707879 = 8707980
  • 103 + 8707877 = 8707980
  • 107 + 8707873 = 8707980
  • 137 + 8707843 = 8707980
  • 139 + 8707841 = 8707980

Showing the first eight; more decompositions exist.
