Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187882, here are decompositions:

  • 5 + 187877 = 187882
  • 11 + 187871 = 187882
  • 59 + 187823 = 187882
  • 89 + 187793 = 187882
  • 131 + 187751 = 187882
  • 251 + 187631 = 187882
  • 419 + 187463 = 187882
  • 449 + 187433 = 187882

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 187,882 and was likely granted around 1875.

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