Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 182542, here are decompositions:

  • 5 + 182537 = 182542
  • 23 + 182519 = 182542
  • 53 + 182489 = 182542
  • 71 + 182471 = 182542
  • 89 + 182453 = 182542
  • 233 + 182309 = 182542
  • 263 + 182279 = 182542
  • 281 + 182261 = 182542

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 182,542 and was likely granted around 1875.

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