Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8736780, here are decompositions:

  • 53 + 8736727 = 8736780
  • 61 + 8736719 = 8736780
  • 79 + 8736701 = 8736780
  • 97 + 8736683 = 8736780
  • 113 + 8736667 = 8736780
  • 127 + 8736653 = 8736780
  • 149 + 8736631 = 8736780
  • 163 + 8736617 = 8736780

Showing the first eight; more decompositions exist.
