Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 182920, here are decompositions:

  • 53 + 182867 = 182920
  • 107 + 182813 = 182920
  • 131 + 182789 = 182920
  • 173 + 182747 = 182920
  • 233 + 182687 = 182920
  • 239 + 182681 = 182920
  • 263 + 182657 = 182920
  • 281 + 182639 = 182920

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 182,920 and was likely granted around 1875.

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