Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621882, here are decompositions:

  • 13 + 8621869 = 8621882
  • 19 + 8621863 = 8621882
  • 103 + 8621779 = 8621882
  • 109 + 8621773 = 8621882
  • 229 + 8621653 = 8621882
  • 331 + 8621551 = 8621882
  • 439 + 8621443 = 8621882
  • 601 + 8621281 = 8621882

Showing the first eight; more decompositions exist.
