Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667564, here are decompositions:

  • 5 + 8667559 = 8667564
  • 43 + 8667521 = 8667564
  • 53 + 8667511 = 8667564
  • 67 + 8667497 = 8667564
  • 107 + 8667457 = 8667564
  • 137 + 8667427 = 8667564
  • 151 + 8667413 = 8667564
  • 193 + 8667371 = 8667564

Showing the first eight; more decompositions exist.
