Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626878, here are decompositions:

  • 17 + 8626861 = 8626878
  • 31 + 8626847 = 8626878
  • 37 + 8626841 = 8626878
  • 47 + 8626831 = 8626878
  • 59 + 8626819 = 8626878
  • 67 + 8626811 = 8626878
  • 101 + 8626777 = 8626878
  • 131 + 8626747 = 8626878

Showing the first eight; more decompositions exist.
