Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33545720, here are decompositions:

  • 7 + 33545713 = 33545720
  • 97 + 33545623 = 33545720
  • 163 + 33545557 = 33545720
  • 193 + 33545527 = 33545720
  • 223 + 33545497 = 33545720
  • 277 + 33545443 = 33545720
  • 331 + 33545389 = 33545720
  • 337 + 33545383 = 33545720

Showing the first eight; more decompositions exist.
