Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671608, here are decompositions:

  • 19 + 8671589 = 8671608
  • 59 + 8671549 = 8671608
  • 89 + 8671519 = 8671608
  • 97 + 8671511 = 8671608
  • 107 + 8671501 = 8671608
  • 109 + 8671499 = 8671608
  • 137 + 8671471 = 8671608
  • 139 + 8671469 = 8671608

Showing the first eight; more decompositions exist.
