Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85718, here are decompositions:

  • 7 + 85711 = 85718
  • 79 + 85639 = 85718
  • 97 + 85621 = 85718
  • 271 + 85447 = 85718
  • 307 + 85411 = 85718
  • 337 + 85381 = 85718
  • 349 + 85369 = 85718
  • 421 + 85297 = 85718

Showing the first eight; more decompositions exist.
