Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 108858, here are decompositions:

  • 31 + 108827 = 108858
  • 37 + 108821 = 108858
  • 59 + 108799 = 108858
  • 67 + 108791 = 108858
  • 89 + 108769 = 108858
  • 97 + 108761 = 108858
  • 107 + 108751 = 108858
  • 131 + 108727 = 108858

Showing the first eight; more decompositions exist.

Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 108,858 and was likely granted around 1871.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
