Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998636, here are decompositions:

  • 3 + 998633 = 998636
  • 7 + 998629 = 998636
  • 13 + 998623 = 998636
  • 19 + 998617 = 998636
  • 97 + 998539 = 998636
  • 109 + 998527 = 998636
  • 139 + 998497 = 998636
  • 193 + 998443 = 998636

Showing the first eight; more decompositions exist.
