Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666804, here are decompositions:

  • 7 + 8666797 = 8666804
  • 31 + 8666773 = 8666804
  • 37 + 8666767 = 8666804
  • 271 + 8666533 = 8666804
  • 313 + 8666491 = 8666804
  • 373 + 8666431 = 8666804
  • 457 + 8666347 = 8666804
  • 631 + 8666173 = 8666804

Showing the first eight; more decompositions exist.
