Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33494872, here are decompositions:

  • 11 + 33494861 = 33494872
  • 53 + 33494819 = 33494872
  • 83 + 33494789 = 33494872
  • 101 + 33494771 = 33494872
  • 113 + 33494759 = 33494872
  • 239 + 33494633 = 33494872
  • 263 + 33494609 = 33494872
  • 293 + 33494579 = 33494872

Showing the first eight; more decompositions exist.
