Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162450, here are decompositions:

  • 11 + 162439 = 162450
  • 31 + 162419 = 162450
  • 37 + 162413 = 162450
  • 59 + 162391 = 162450
  • 61 + 162389 = 162450
  • 107 + 162343 = 162450
  • 157 + 162293 = 162450
  • 163 + 162287 = 162450

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 162,450 and was likely granted around 1874.

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