Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722510, here are decompositions:

  • 11 + 8722499 = 8722510
  • 101 + 8722409 = 8722510
  • 149 + 8722361 = 8722510
  • 179 + 8722331 = 8722510
  • 227 + 8722283 = 8722510
  • 317 + 8722193 = 8722510
  • 431 + 8722079 = 8722510
  • 491 + 8722019 = 8722510

Showing the first eight; more decompositions exist.
