Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626872, here are decompositions:

  • 11 + 8626861 = 8626872
  • 31 + 8626841 = 8626872
  • 41 + 8626831 = 8626872
  • 53 + 8626819 = 8626872
  • 61 + 8626811 = 8626872
  • 71 + 8626801 = 8626872
  • 109 + 8626763 = 8626872
  • 139 + 8626733 = 8626872

Showing the first eight; more decompositions exist.
