Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581600, here are decompositions:

  • 79 + 33581521 = 33581600
  • 109 + 33581491 = 33581600
  • 163 + 33581437 = 33581600
  • 271 + 33581329 = 33581600
  • 313 + 33581287 = 33581600
  • 337 + 33581263 = 33581600
  • 379 + 33581221 = 33581600
  • 607 + 33580993 = 33581600

Showing the first eight; more decompositions exist.
