Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33571228, here are decompositions:

  • 17 + 33571211 = 33571228
  • 107 + 33571121 = 33571228
  • 137 + 33571091 = 33571228
  • 149 + 33571079 = 33571228
  • 179 + 33571049 = 33571228
  • 191 + 33571037 = 33571228
  • 347 + 33570881 = 33571228
  • 419 + 33570809 = 33571228

Showing the first eight; more decompositions exist.
