Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 182378, here are decompositions:

  • 37 + 182341 = 182378
  • 139 + 182239 = 182378
  • 199 + 182179 = 182378
  • 211 + 182167 = 182378
  • 271 + 182107 = 182378
  • 277 + 182101 = 182378
  • 331 + 182047 = 182378
  • 337 + 182041 = 182378

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 182,378 and was likely granted around 1875.

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