Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8713720, here are decompositions:

  • 11 + 8713709 = 8713720
  • 89 + 8713631 = 8713720
  • 137 + 8713583 = 8713720
  • 167 + 8713553 = 8713720
  • 173 + 8713547 = 8713720
  • 233 + 8713487 = 8713720
  • 269 + 8713451 = 8713720
  • 317 + 8713403 = 8713720

Showing the first eight; more decompositions exist.
