Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180310, here are decompositions:

  • 3 + 180307 = 180310
  • 23 + 180287 = 180310
  • 29 + 180281 = 180310
  • 47 + 180263 = 180310
  • 71 + 180239 = 180310
  • 89 + 180221 = 180310
  • 131 + 180179 = 180310
  • 149 + 180161 = 180310

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 180,310 and was likely granted around 1875.

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