Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8705784, here are decompositions:

  • 7 + 8705777 = 8705784
  • 11 + 8705773 = 8705784
  • 37 + 8705747 = 8705784
  • 103 + 8705681 = 8705784
  • 127 + 8705657 = 8705784
  • 167 + 8705617 = 8705784
  • 173 + 8705611 = 8705784
  • 211 + 8705573 = 8705784

Showing the first eight; more decompositions exist.
