Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33572160, here are decompositions:

  • 19 + 33572141 = 33572160
  • 29 + 33572131 = 33572160
  • 43 + 33572117 = 33572160
  • 79 + 33572081 = 33572160
  • 109 + 33572051 = 33572160
  • 131 + 33572029 = 33572160
  • 151 + 33572009 = 33572160
  • 163 + 33571997 = 33572160

Showing the first eight; more decompositions exist.
