Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626690, here are decompositions:

  • 47 + 8626643 = 8626690
  • 113 + 8626577 = 8626690
  • 173 + 8626517 = 8626690
  • 197 + 8626493 = 8626690
  • 269 + 8626421 = 8626690
  • 389 + 8626301 = 8626690
  • 419 + 8626271 = 8626690
  • 461 + 8626229 = 8626690

Showing the first eight; more decompositions exist.
