Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33565240, here are decompositions:

  • 17 + 33565223 = 33565240
  • 41 + 33565199 = 33565240
  • 179 + 33565061 = 33565240
  • 197 + 33565043 = 33565240
  • 281 + 33564959 = 33565240
  • 347 + 33564893 = 33565240
  • 479 + 33564761 = 33565240
  • 503 + 33564737 = 33565240

Showing the first eight; more decompositions exist.
