Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638950, here are decompositions:

  • 13 + 8638937 = 8638950
  • 17 + 8638933 = 8638950
  • 41 + 8638909 = 8638950
  • 59 + 8638891 = 8638950
  • 83 + 8638867 = 8638950
  • 97 + 8638853 = 8638950
  • 101 + 8638849 = 8638950
  • 107 + 8638843 = 8638950

Showing the first eight; more decompositions exist.
