Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3556, here are decompositions:

  • 17 + 3539 = 3556
  • 23 + 3533 = 3556
  • 29 + 3527 = 3556
  • 89 + 3467 = 3556
  • 107 + 3449 = 3556
  • 149 + 3407 = 3556
  • 167 + 3389 = 3556
  • 197 + 3359 = 3556

Showing the first eight; more decompositions exist.
