Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91886, here are decompositions:

  • 13 + 91873 = 91886
  • 19 + 91867 = 91886
  • 73 + 91813 = 91886
  • 79 + 91807 = 91886
  • 313 + 91573 = 91886
  • 373 + 91513 = 91886
  • 433 + 91453 = 91886
  • 463 + 91423 = 91886

Showing the first eight; more decompositions exist.
