Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738040, here are decompositions:

  • 7 + 8738033 = 8738040
  • 29 + 8738011 = 8738040
  • 61 + 8737979 = 8738040
  • 97 + 8737943 = 8738040
  • 107 + 8737933 = 8738040
  • 167 + 8737873 = 8738040
  • 173 + 8737867 = 8738040
  • 191 + 8737849 = 8738040

Showing the first eight; more decompositions exist.
