Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8619904, here are decompositions:

  • 11 + 8619893 = 8619904
  • 47 + 8619857 = 8619904
  • 107 + 8619797 = 8619904
  • 113 + 8619791 = 8619904
  • 131 + 8619773 = 8619904
  • 191 + 8619713 = 8619904
  • 281 + 8619623 = 8619904
  • 311 + 8619593 = 8619904

Showing the first eight; more decompositions exist.
