Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85858, here are decompositions:

  • 5 + 85853 = 85858
  • 11 + 85847 = 85858
  • 29 + 85829 = 85858
  • 41 + 85817 = 85858
  • 107 + 85751 = 85858
  • 167 + 85691 = 85858
  • 191 + 85667 = 85858
  • 197 + 85661 = 85858

Showing the first eight; more decompositions exist.
