Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 170838, here are decompositions:

  • 11 + 170827 = 170838
  • 29 + 170809 = 170838
  • 37 + 170801 = 170838
  • 61 + 170777 = 170838
  • 71 + 170767 = 170838
  • 79 + 170759 = 170838
  • 89 + 170749 = 170838
  • 97 + 170741 = 170838

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 170,838 and was likely granted around 1874.

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