Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679888, here are decompositions:

  • 5 + 8679883 = 8679888
  • 17 + 8679871 = 8679888
  • 47 + 8679841 = 8679888
  • 97 + 8679791 = 8679888
  • 149 + 8679739 = 8679888
  • 179 + 8679709 = 8679888
  • 211 + 8679677 = 8679888
  • 271 + 8679617 = 8679888

Showing the first eight; more decompositions exist.
