Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 157450, here are decompositions:

  • 17 + 157433 = 157450
  • 23 + 157427 = 157450
  • 101 + 157349 = 157450
  • 173 + 157277 = 157450
  • 179 + 157271 = 157450
  • 191 + 157259 = 157450
  • 197 + 157253 = 157450
  • 233 + 157217 = 157450

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 157,450 and was likely granted around 1873.

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