Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667040, here are decompositions:

  • 47 + 8666993 = 8667040
  • 101 + 8666939 = 8667040
  • 113 + 8666927 = 8667040
  • 149 + 8666891 = 8667040
  • 191 + 8666849 = 8667040
  • 233 + 8666807 = 8667040
  • 257 + 8666783 = 8667040
  • 293 + 8666747 = 8667040

Showing the first eight; more decompositions exist.
