Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33599520, here are decompositions:

  • 67 + 33599453 = 33599520
  • 89 + 33599431 = 33599520
  • 103 + 33599417 = 33599520
  • 179 + 33599341 = 33599520
  • 181 + 33599339 = 33599520
  • 197 + 33599323 = 33599520
  • 211 + 33599309 = 33599520
  • 239 + 33599281 = 33599520

Showing the first eight; more decompositions exist.
