Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33510840, here are decompositions:

  • 7 + 33510833 = 33510840
  • 19 + 33510821 = 33510840
  • 43 + 33510797 = 33510840
  • 59 + 33510781 = 33510840
  • 61 + 33510779 = 33510840
  • 73 + 33510767 = 33510840
  • 89 + 33510751 = 33510840
  • 101 + 33510739 = 33510840

Showing the first eight; more decompositions exist.
