Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647450, here are decompositions:

  • 3 + 8647447 = 8647450
  • 41 + 8647409 = 8647450
  • 59 + 8647391 = 8647450
  • 83 + 8647367 = 8647450
  • 101 + 8647349 = 8647450
  • 173 + 8647277 = 8647450
  • 197 + 8647253 = 8647450
  • 257 + 8647193 = 8647450

Showing the first eight; more decompositions exist.
