Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638892, here are decompositions:

  • 43 + 8638849 = 8638892
  • 271 + 8638621 = 8638892
  • 349 + 8638543 = 8638892
  • 421 + 8638471 = 8638892
  • 439 + 8638453 = 8638892
  • 601 + 8638291 = 8638892
  • 673 + 8638219 = 8638892
  • 709 + 8638183 = 8638892

Showing the first eight; more decompositions exist.
