Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162558, here are decompositions:

  • 5 + 162553 = 162558
  • 29 + 162529 = 162558
  • 31 + 162527 = 162558
  • 41 + 162517 = 162558
  • 59 + 162499 = 162558
  • 101 + 162457 = 162558
  • 107 + 162451 = 162558
  • 139 + 162419 = 162558

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 162,558 and was likely granted around 1874.

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