Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22856, here are decompositions:

  • 3 + 22853 = 22856
  • 73 + 22783 = 22856
  • 79 + 22777 = 22856
  • 139 + 22717 = 22856
  • 157 + 22699 = 22856
  • 283 + 22573 = 22856
  • 307 + 22549 = 22856
  • 313 + 22543 = 22856

Showing the first eight; more decompositions exist.
