Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624890, here are decompositions:

  • 3 + 8624887 = 8624890
  • 17 + 8624873 = 8624890
  • 83 + 8624807 = 8624890
  • 137 + 8624753 = 8624890
  • 173 + 8624717 = 8624890
  • 257 + 8624633 = 8624890
  • 269 + 8624621 = 8624890
  • 317 + 8624573 = 8624890

Showing the first eight; more decompositions exist.
