Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 190438, here are decompositions:

  • 29 + 190409 = 190438
  • 47 + 190391 = 190438
  • 71 + 190367 = 190438
  • 107 + 190331 = 190438
  • 137 + 190301 = 190438
  • 167 + 190271 = 190438
  • 257 + 190181 = 190438
  • 317 + 190121 = 190438

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 190,438 and was likely granted around 1875.

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