Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33479160, here are decompositions:

  • 19 + 33479141 = 33479160
  • 41 + 33479119 = 33479160
  • 53 + 33479107 = 33479160
  • 97 + 33479063 = 33479160
  • 149 + 33479011 = 33479160
  • 157 + 33479003 = 33479160
  • 179 + 33478981 = 33479160
  • 181 + 33478979 = 33479160

Showing the first eight; more decompositions exist.
