Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624742, here are decompositions:

  • 29 + 8624713 = 8624742
  • 73 + 8624669 = 8624742
  • 109 + 8624633 = 8624742
  • 239 + 8624503 = 8624742
  • 283 + 8624459 = 8624742
  • 293 + 8624449 = 8624742
  • 349 + 8624393 = 8624742
  • 359 + 8624383 = 8624742

Showing the first eight; more decompositions exist.
