Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 190542, here are decompositions:

  • 5 + 190537 = 190542
  • 13 + 190529 = 190542
  • 19 + 190523 = 190542
  • 71 + 190471 = 190542
  • 139 + 190403 = 190542
  • 151 + 190391 = 190542
  • 173 + 190369 = 190542
  • 211 + 190331 = 190542

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 190,542 and was likely granted around 1875.

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