Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33587920, here are decompositions:

  • 53 + 33587867 = 33587920
  • 89 + 33587831 = 33587920
  • 131 + 33587789 = 33587920
  • 251 + 33587669 = 33587920
  • 383 + 33587537 = 33587920
  • 449 + 33587471 = 33587920
  • 503 + 33587417 = 33587920
  • 557 + 33587363 = 33587920

Showing the first eight; more decompositions exist.
