Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33572400, here are decompositions:

  • 19 + 33572381 = 33572400
  • 23 + 33572377 = 33572400
  • 47 + 33572353 = 33572400
  • 53 + 33572347 = 33572400
  • 61 + 33572339 = 33572400
  • 67 + 33572333 = 33572400
  • 89 + 33572311 = 33572400
  • 97 + 33572303 = 33572400

Showing the first eight; more decompositions exist.
