Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91858, here are decompositions:

  • 17 + 91841 = 91858
  • 47 + 91811 = 91858
  • 101 + 91757 = 91858
  • 167 + 91691 = 91858
  • 227 + 91631 = 91858
  • 281 + 91577 = 91858
  • 317 + 91541 = 91858
  • 359 + 91499 = 91858

Showing the first eight; more decompositions exist.
