Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639146, here are decompositions:

  • 3 + 8639143 = 8639146
  • 23 + 8639123 = 8639146
  • 83 + 8639063 = 8639146
  • 149 + 8638997 = 8639146
  • 179 + 8638967 = 8639146
  • 293 + 8638853 = 8639146
  • 419 + 8638727 = 8639146
  • 449 + 8638697 = 8639146

Showing the first eight; more decompositions exist.
