Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542188, here are decompositions:

  • 5 + 542183 = 542188
  • 47 + 542141 = 542188
  • 71 + 542117 = 542188
  • 107 + 542081 = 542188
  • 167 + 542021 = 542188
  • 197 + 541991 = 542188
  • 389 + 541799 = 542188
  • 461 + 541727 = 542188

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 542,188 and was likely granted around 1895.

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