Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33481872, here are decompositions:

  • 19 + 33481853 = 33481872
  • 41 + 33481831 = 33481872
  • 71 + 33481801 = 33481872
  • 89 + 33481783 = 33481872
  • 103 + 33481769 = 33481872
  • 113 + 33481759 = 33481872
  • 373 + 33481499 = 33481872
  • 401 + 33481471 = 33481872

Showing the first eight; more decompositions exist.
