Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8741220, here are decompositions:

  • 17 + 8741203 = 8741220
  • 29 + 8741191 = 8741220
  • 67 + 8741153 = 8741220
  • 71 + 8741149 = 8741220
  • 73 + 8741147 = 8741220
  • 79 + 8741141 = 8741220
  • 83 + 8741137 = 8741220
  • 97 + 8741123 = 8741220

Showing the first eight; more decompositions exist.
