Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2636, here are decompositions:

  • 3 + 2633 = 2636
  • 19 + 2617 = 2636
  • 43 + 2593 = 2636
  • 79 + 2557 = 2636
  • 97 + 2539 = 2636
  • 163 + 2473 = 2636
  • 199 + 2437 = 2636
  • 349 + 2287 = 2636

Showing the first eight; more decompositions exist.
