Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33605880, here are decompositions:

  • 17 + 33605863 = 33605880
  • 31 + 33605849 = 33605880
  • 37 + 33605843 = 33605880
  • 41 + 33605839 = 33605880
  • 43 + 33605837 = 33605880
  • 73 + 33605807 = 33605880
  • 83 + 33605797 = 33605880
  • 131 + 33605749 = 33605880

Showing the first eight; more decompositions exist.
