Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 169478, here are decompositions:

  • 7 + 169471 = 169478
  • 79 + 169399 = 169478
  • 109 + 169369 = 169478
  • 139 + 169339 = 169478
  • 151 + 169327 = 169478
  • 157 + 169321 = 169478
  • 229 + 169249 = 169478
  • 349 + 169129 = 169478

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 169,478 and was likely granted around 1874.

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