Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33507560, here are decompositions:

  • 19 + 33507541 = 33507560
  • 181 + 33507379 = 33507560
  • 241 + 33507319 = 33507560
  • 313 + 33507247 = 33507560
  • 337 + 33507223 = 33507560
  • 349 + 33507211 = 33507560
  • 439 + 33507121 = 33507560
  • 523 + 33507037 = 33507560

Showing the first eight; more decompositions exist.
