Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938842, here are decompositions:

  • 11 + 938831 = 938842
  • 251 + 938591 = 938842
  • 269 + 938573 = 938842
  • 383 + 938459 = 938842
  • 389 + 938453 = 938842
  • 449 + 938393 = 938842
  • 491 + 938351 = 938842
  • 563 + 938279 = 938842

Showing the first eight; more decompositions exist.
