Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660500, here are decompositions:

  • 113 + 8660387 = 8660500
  • 131 + 8660369 = 8660500
  • 311 + 8660189 = 8660500
  • 419 + 8660081 = 8660500
  • 449 + 8660051 = 8660500
  • 461 + 8660039 = 8660500
  • 467 + 8660033 = 8660500
  • 503 + 8659997 = 8660500

Showing the first eight; more decompositions exist.
