Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33545648, here are decompositions:

  • 151 + 33545497 = 33545648
  • 271 + 33545377 = 33545648
  • 277 + 33545371 = 33545648
  • 337 + 33545311 = 33545648
  • 397 + 33545251 = 33545648
  • 421 + 33545227 = 33545648
  • 457 + 33545191 = 33545648
  • 547 + 33545101 = 33545648

Showing the first eight; more decompositions exist.
