Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624740, here are decompositions:

  • 23 + 8624717 = 8624740
  • 71 + 8624669 = 8624740
  • 107 + 8624633 = 8624740
  • 167 + 8624573 = 8624740
  • 233 + 8624507 = 8624740
  • 263 + 8624477 = 8624740
  • 281 + 8624459 = 8624740
  • 347 + 8624393 = 8624740

Showing the first eight; more decompositions exist.
