Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8662878, here are decompositions:

  • 11 + 8662867 = 8662878
  • 19 + 8662859 = 8662878
  • 47 + 8662831 = 8662878
  • 67 + 8662811 = 8662878
  • 71 + 8662807 = 8662878
  • 79 + 8662799 = 8662878
  • 109 + 8662769 = 8662878
  • 127 + 8662751 = 8662878

Showing the first eight; more decompositions exist.
