Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33571640, here are decompositions:

  • 7 + 33571633 = 33571640
  • 13 + 33571627 = 33571640
  • 31 + 33571609 = 33571640
  • 43 + 33571597 = 33571640
  • 313 + 33571327 = 33571640
  • 337 + 33571303 = 33571640
  • 373 + 33571267 = 33571640
  • 577 + 33571063 = 33571640

Showing the first eight; more decompositions exist.
