Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85518, here are decompositions:

  • 5 + 85513 = 85518
  • 31 + 85487 = 85518
  • 67 + 85451 = 85518
  • 71 + 85447 = 85518
  • 79 + 85439 = 85518
  • 89 + 85429 = 85518
  • 107 + 85411 = 85518
  • 137 + 85381 = 85518

Showing the first eight; more decompositions exist.
