Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722250, here are decompositions:

  • 13 + 8722237 = 8722250
  • 79 + 8722171 = 8722250
  • 127 + 8722123 = 8722250
  • 151 + 8722099 = 8722250
  • 157 + 8722093 = 8722250
  • 223 + 8722027 = 8722250
  • 241 + 8722009 = 8722250
  • 337 + 8721913 = 8722250

Showing the first eight; more decompositions exist.
