Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722408, here are decompositions:

  • 17 + 8722391 = 8722408
  • 41 + 8722367 = 8722408
  • 47 + 8722361 = 8722408
  • 197 + 8722211 = 8722408
  • 239 + 8722169 = 8722408
  • 311 + 8722097 = 8722408
  • 389 + 8722019 = 8722408
  • 419 + 8721989 = 8722408

Showing the first eight; more decompositions exist.
