Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171312, here are decompositions:

  • 13 + 171299 = 171312
  • 19 + 171293 = 171312
  • 41 + 171271 = 171312
  • 59 + 171253 = 171312
  • 61 + 171251 = 171312
  • 79 + 171233 = 171312
  • 109 + 171203 = 171312
  • 149 + 171163 = 171312

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 171,312 and was likely granted around 1874.

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