Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722270, here are decompositions:

  • 47 + 8722223 = 8722270
  • 59 + 8722211 = 8722270
  • 83 + 8722187 = 8722270
  • 101 + 8722169 = 8722270
  • 173 + 8722097 = 8722270
  • 191 + 8722079 = 8722270
  • 251 + 8722019 = 8722270
  • 269 + 8722001 = 8722270

Showing the first eight; more decompositions exist.
