Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33525760, here are decompositions:

  • 3 + 33525757 = 33525760
  • 29 + 33525731 = 33525760
  • 53 + 33525707 = 33525760
  • 113 + 33525647 = 33525760
  • 167 + 33525593 = 33525760
  • 227 + 33525533 = 33525760
  • 269 + 33525491 = 33525760
  • 311 + 33525449 = 33525760

Showing the first eight; more decompositions exist.
