Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626816, here are decompositions:

  • 5 + 8626811 = 8626816
  • 53 + 8626763 = 8626816
  • 83 + 8626733 = 8626816
  • 173 + 8626643 = 8626816
  • 239 + 8626577 = 8626816
  • 347 + 8626469 = 8626816
  • 467 + 8626349 = 8626816
  • 587 + 8626229 = 8626816

Showing the first eight; more decompositions exist.
