Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8608642, here are decompositions:

  • 23 + 8608619 = 8608642
  • 59 + 8608583 = 8608642
  • 71 + 8608571 = 8608642
  • 89 + 8608553 = 8608642
  • 113 + 8608529 = 8608642
  • 191 + 8608451 = 8608642
  • 269 + 8608373 = 8608642
  • 401 + 8608241 = 8608642

Showing the first eight; more decompositions exist.
