Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8619804, here are decompositions:

  • 7 + 8619797 = 8619804
  • 13 + 8619791 = 8619804
  • 31 + 8619773 = 8619804
  • 181 + 8619623 = 8619804
  • 211 + 8619593 = 8619804
  • 293 + 8619511 = 8619804
  • 313 + 8619491 = 8619804
  • 331 + 8619473 = 8619804

Showing the first eight; more decompositions exist.
