Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 163558, here are decompositions:

  • 41 + 163517 = 163558
  • 71 + 163487 = 163558
  • 89 + 163469 = 163558
  • 149 + 163409 = 163558
  • 191 + 163367 = 163558
  • 251 + 163307 = 163558
  • 347 + 163211 = 163558
  • 359 + 163199 = 163558

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 163,558 and was likely granted around 1874.

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