Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33488520, here are decompositions:

  • 11 + 33488509 = 33488520
  • 19 + 33488501 = 33488520
  • 29 + 33488491 = 33488520
  • 41 + 33488479 = 33488520
  • 53 + 33488467 = 33488520
  • 59 + 33488461 = 33488520
  • 71 + 33488449 = 33488520
  • 113 + 33488407 = 33488520

Showing the first eight; more decompositions exist.
