Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55638, here are decompositions:

  • 5 + 55633 = 55638
  • 7 + 55631 = 55638
  • 17 + 55621 = 55638
  • 19 + 55619 = 55638
  • 29 + 55609 = 55638
  • 59 + 55579 = 55638
  • 97 + 55541 = 55638
  • 109 + 55529 = 55638

Showing the first eight; more decompositions exist.
