Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86558, here are decompositions:

  • 19 + 86539 = 86558
  • 67 + 86491 = 86558
  • 97 + 86461 = 86558
  • 271 + 86287 = 86558
  • 349 + 86209 = 86558
  • 379 + 86179 = 86558
  • 397 + 86161 = 86558
  • 421 + 86137 = 86558

Showing the first eight; more decompositions exist.
