Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33481440, here are decompositions:

  • 11 + 33481429 = 33481440
  • 17 + 33481423 = 33481440
  • 43 + 33481397 = 33481440
  • 71 + 33481369 = 33481440
  • 73 + 33481367 = 33481440
  • 79 + 33481361 = 33481440
  • 89 + 33481351 = 33481440
  • 101 + 33481339 = 33481440

Showing the first eight; more decompositions exist.
