Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8619178, here are decompositions:

  • 11 + 8619167 = 8619178
  • 47 + 8619131 = 8619178
  • 101 + 8619077 = 8619178
  • 107 + 8619071 = 8619178
  • 137 + 8619041 = 8619178
  • 179 + 8618999 = 8619178
  • 311 + 8618867 = 8619178
  • 317 + 8618861 = 8619178

Showing the first eight; more decompositions exist.
