Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188418, here are decompositions:

  • 11 + 188407 = 188418
  • 17 + 188401 = 188418
  • 29 + 188389 = 188418
  • 59 + 188359 = 188418
  • 67 + 188351 = 188418
  • 101 + 188317 = 188418
  • 107 + 188311 = 188418
  • 127 + 188291 = 188418

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 188,418 and was likely granted around 1875.

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