Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666470, here are decompositions:

  • 11 + 8666459 = 8666470
  • 53 + 8666417 = 8666470
  • 83 + 8666387 = 8666470
  • 89 + 8666381 = 8666470
  • 101 + 8666369 = 8666470
  • 179 + 8666291 = 8666470
  • 233 + 8666237 = 8666470
  • 251 + 8666219 = 8666470

Showing the first eight; more decompositions exist.
