Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621494, here are decompositions:

  • 3 + 8621491 = 8621494
  • 17 + 8621477 = 8621494
  • 41 + 8621453 = 8621494
  • 83 + 8621411 = 8621494
  • 251 + 8621243 = 8621494
  • 257 + 8621237 = 8621494
  • 281 + 8621213 = 8621494
  • 293 + 8621201 = 8621494

Showing the first eight; more decompositions exist.
