Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643956, here are decompositions:

  • 3 + 8643953 = 8643956
  • 37 + 8643919 = 8643956
  • 67 + 8643889 = 8643956
  • 199 + 8643757 = 8643956
  • 283 + 8643673 = 8643956
  • 337 + 8643619 = 8643956
  • 367 + 8643589 = 8643956
  • 379 + 8643577 = 8643956

Showing the first eight; more decompositions exist.
