Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636742, here are decompositions:

  • 5 + 8636737 = 8636742
  • 29 + 8636713 = 8636742
  • 41 + 8636701 = 8636742
  • 53 + 8636689 = 8636742
  • 71 + 8636671 = 8636742
  • 109 + 8636633 = 8636742
  • 139 + 8636603 = 8636742
  • 151 + 8636591 = 8636742

Showing the first eight; more decompositions exist.
