Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43520, here are decompositions:

  • 3 + 43517 = 43520
  • 79 + 43441 = 43520
  • 109 + 43411 = 43520
  • 199 + 43321 = 43520
  • 229 + 43291 = 43520
  • 283 + 43237 = 43520
  • 313 + 43207 = 43520
  • 331 + 43189 = 43520

Showing the first eight; more decompositions exist.
