Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707984, here are decompositions:

  • 101 + 8707883 = 8707984
  • 107 + 8707877 = 8707984
  • 167 + 8707817 = 8707984
  • 191 + 8707793 = 8707984
  • 353 + 8707631 = 8707984
  • 563 + 8707421 = 8707984
  • 641 + 8707343 = 8707984
  • 743 + 8707241 = 8707984

Showing the first eight; more decompositions exist.
