Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8673984, here are decompositions:

  • 31 + 8673953 = 8673984
  • 43 + 8673941 = 8673984
  • 61 + 8673923 = 8673984
  • 71 + 8673913 = 8673984
  • 73 + 8673911 = 8673984
  • 83 + 8673901 = 8673984
  • 107 + 8673877 = 8673984
  • 167 + 8673817 = 8673984

Showing the first eight; more decompositions exist.
