Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38678, here are decompositions:

  • 7 + 38671 = 38678
  • 67 + 38611 = 38678
  • 109 + 38569 = 38678
  • 229 + 38449 = 38678
  • 307 + 38371 = 38678
  • 349 + 38329 = 38678
  • 379 + 38299 = 38678
  • 397 + 38281 = 38678

Showing the first eight; more decompositions exist.
