Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649936, here are decompositions:

  • 7 + 8649929 = 8649936
  • 67 + 8649869 = 8649936
  • 79 + 8649857 = 8649936
  • 83 + 8649853 = 8649936
  • 89 + 8649847 = 8649936
  • 173 + 8649763 = 8649936
  • 179 + 8649757 = 8649936
  • 233 + 8649703 = 8649936

Showing the first eight; more decompositions exist.
