Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626840, here are decompositions:

  • 17 + 8626823 = 8626840
  • 29 + 8626811 = 8626840
  • 107 + 8626733 = 8626840
  • 149 + 8626691 = 8626840
  • 197 + 8626643 = 8626840
  • 227 + 8626613 = 8626840
  • 263 + 8626577 = 8626840
  • 311 + 8626529 = 8626840

Showing the first eight; more decompositions exist.
