Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561888, here are decompositions:

  • 7 + 33561881 = 33561888
  • 11 + 33561877 = 33561888
  • 37 + 33561851 = 33561888
  • 71 + 33561817 = 33561888
  • 89 + 33561799 = 33561888
  • 109 + 33561779 = 33561888
  • 137 + 33561751 = 33561888
  • 277 + 33561611 = 33561888

Showing the first eight; more decompositions exist.
