Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668928, here are decompositions:

  • 31 + 8668897 = 8668928
  • 97 + 8668831 = 8668928
  • 127 + 8668801 = 8668928
  • 241 + 8668687 = 8668928
  • 379 + 8668549 = 8668928
  • 409 + 8668519 = 8668928
  • 439 + 8668489 = 8668928
  • 547 + 8668381 = 8668928

Showing the first eight; more decompositions exist.
