Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172424, here are decompositions:

  • 3 + 172421 = 172424
  • 13 + 172411 = 172424
  • 67 + 172357 = 172424
  • 73 + 172351 = 172424
  • 103 + 172321 = 172424
  • 127 + 172297 = 172424
  • 181 + 172243 = 172424
  • 211 + 172213 = 172424

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 172,424 and was likely granted around 1874.

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