Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43428, here are decompositions:

  • 17 + 43411 = 43428
  • 29 + 43399 = 43428
  • 31 + 43397 = 43428
  • 37 + 43391 = 43428
  • 97 + 43331 = 43428
  • 107 + 43321 = 43428
  • 109 + 43319 = 43428
  • 137 + 43291 = 43428

Showing the first eight; more decompositions exist.
