Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8605620, here are decompositions:

  • 11 + 8605609 = 8605620
  • 13 + 8605607 = 8605620
  • 19 + 8605601 = 8605620
  • 43 + 8605577 = 8605620
  • 53 + 8605567 = 8605620
  • 59 + 8605561 = 8605620
  • 109 + 8605511 = 8605620
  • 139 + 8605481 = 8605620

Showing the first eight; more decompositions exist.
