Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636784, here are decompositions:

  • 5 + 8636779 = 8636784
  • 43 + 8636741 = 8636784
  • 47 + 8636737 = 8636784
  • 71 + 8636713 = 8636784
  • 83 + 8636701 = 8636784
  • 113 + 8636671 = 8636784
  • 137 + 8636647 = 8636784
  • 151 + 8636633 = 8636784

Showing the first eight; more decompositions exist.
