Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 169858, here are decompositions:

  • 41 + 169817 = 169858
  • 89 + 169769 = 169858
  • 107 + 169751 = 169858
  • 149 + 169709 = 169858
  • 167 + 169691 = 169858
  • 191 + 169667 = 169858
  • 197 + 169661 = 169858
  • 251 + 169607 = 169858

Showing the first eight; more decompositions exist.
