Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722448, here are decompositions:

  • 19 + 8722429 = 8722448
  • 109 + 8722339 = 8722448
  • 151 + 8722297 = 8722448
  • 157 + 8722291 = 8722448
  • 211 + 8722237 = 8722448
  • 277 + 8722171 = 8722448
  • 331 + 8722117 = 8722448
  • 349 + 8722099 = 8722448

Showing the first eight; more decompositions exist.
