Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33539620, here are decompositions:

  • 17 + 33539603 = 33539620
  • 29 + 33539591 = 33539620
  • 53 + 33539567 = 33539620
  • 71 + 33539549 = 33539620
  • 89 + 33539531 = 33539620
  • 227 + 33539393 = 33539620
  • 263 + 33539357 = 33539620
  • 311 + 33539309 = 33539620

Showing the first eight; more decompositions exist.
