Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187600, here are decompositions:

  • 3 + 187597 = 187600
  • 41 + 187559 = 187600
  • 53 + 187547 = 187600
  • 131 + 187469 = 187600
  • 137 + 187463 = 187600
  • 167 + 187433 = 187600
  • 191 + 187409 = 187600
  • 227 + 187373 = 187600

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 187,600 and was likely granted around 1875.

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