Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172654, here are decompositions:

  • 5 + 172649 = 172654
  • 11 + 172643 = 172654
  • 47 + 172607 = 172654
  • 71 + 172583 = 172654
  • 101 + 172553 = 172654
  • 113 + 172541 = 172654
  • 137 + 172517 = 172654
  • 227 + 172427 = 172654

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 172,654 and was likely granted around 1874.

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