Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622280, here are decompositions:

  • 71 + 8622209 = 8622280
  • 89 + 8622191 = 8622280
  • 167 + 8622113 = 8622280
  • 239 + 8622041 = 8622280
  • 257 + 8622023 = 8622280
  • 263 + 8622017 = 8622280
  • 269 + 8622011 = 8622280
  • 347 + 8621933 = 8622280

Showing the first eight; more decompositions exist.
