Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679744, here are decompositions:

  • 5 + 8679739 = 8679744
  • 67 + 8679677 = 8679744
  • 103 + 8679641 = 8679744
  • 127 + 8679617 = 8679744
  • 137 + 8679607 = 8679744
  • 163 + 8679581 = 8679744
  • 193 + 8679551 = 8679744
  • 317 + 8679427 = 8679744

Showing the first eight; more decompositions exist.
