Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33525020, here are decompositions:

  • 3 + 33525017 = 33525020
  • 7 + 33525013 = 33525020
  • 43 + 33524977 = 33525020
  • 211 + 33524809 = 33525020
  • 367 + 33524653 = 33525020
  • 379 + 33524641 = 33525020
  • 421 + 33524599 = 33525020
  • 433 + 33524587 = 33525020

Showing the first eight; more decompositions exist.
