Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8516, here are decompositions:

  • 3 + 8513 = 8516
  • 73 + 8443 = 8516
  • 97 + 8419 = 8516
  • 127 + 8389 = 8516
  • 139 + 8377 = 8516
  • 163 + 8353 = 8516
  • 199 + 8317 = 8516
  • 223 + 8293 = 8516

Showing the first eight; more decompositions exist.
