Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33545656, here are decompositions:

  • 5 + 33545651 = 33545656
  • 47 + 33545609 = 33545656
  • 59 + 33545597 = 33545656
  • 173 + 33545483 = 33545656
  • 197 + 33545459 = 33545656
  • 227 + 33545429 = 33545656
  • 233 + 33545423 = 33545656
  • 449 + 33545207 = 33545656

Showing the first eight; more decompositions exist.
