Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521160, here are decompositions:

  • 19 + 33521141 = 33521160
  • 61 + 33521099 = 33521160
  • 73 + 33521087 = 33521160
  • 103 + 33521057 = 33521160
  • 139 + 33521021 = 33521160
  • 151 + 33521009 = 33521160
  • 157 + 33521003 = 33521160
  • 173 + 33520987 = 33521160

Showing the first eight; more decompositions exist.
