Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33525072, here are decompositions:

  • 11 + 33525061 = 33525072
  • 13 + 33525059 = 33525072
  • 23 + 33525049 = 33525072
  • 59 + 33525013 = 33525072
  • 73 + 33524999 = 33525072
  • 101 + 33524971 = 33525072
  • 109 + 33524963 = 33525072
  • 181 + 33524891 = 33525072

Showing the first eight; more decompositions exist.
