Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33587520, here are decompositions:

  • 7 + 33587513 = 33587520
  • 11 + 33587509 = 33587520
  • 13 + 33587507 = 33587520
  • 17 + 33587503 = 33587520
  • 41 + 33587479 = 33587520
  • 103 + 33587417 = 33587520
  • 149 + 33587371 = 33587520
  • 157 + 33587363 = 33587520

Showing the first eight; more decompositions exist.
