Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618998, here are decompositions:

  • 131 + 8618867 = 8618998
  • 137 + 8618861 = 8618998
  • 239 + 8618759 = 8618998
  • 251 + 8618747 = 8618998
  • 317 + 8618681 = 8618998
  • 359 + 8618639 = 8618998
  • 431 + 8618567 = 8618998
  • 569 + 8618429 = 8618998

Showing the first eight; more decompositions exist.
