Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645004, here are decompositions:

  • 13 + 8644991 = 8645004
  • 41 + 8644963 = 8645004
  • 47 + 8644957 = 8645004
  • 101 + 8644903 = 8645004
  • 131 + 8644873 = 8645004
  • 223 + 8644781 = 8645004
  • 233 + 8644771 = 8645004
  • 281 + 8644723 = 8645004

Showing the first eight; more decompositions exist.
