Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647882, here are decompositions:

  • 3 + 8647879 = 8647882
  • 59 + 8647823 = 8647882
  • 293 + 8647589 = 8647882
  • 491 + 8647391 = 8647882
  • 653 + 8647229 = 8647882
  • 701 + 8647181 = 8647882
  • 743 + 8647139 = 8647882
  • 821 + 8647061 = 8647882

Showing the first eight; more decompositions exist.
