Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148378, here are decompositions:

  • 11 + 148367 = 148378
  • 17 + 148361 = 148378
  • 47 + 148331 = 148378
  • 149 + 148229 = 148378
  • 179 + 148199 = 148378
  • 227 + 148151 = 148378
  • 239 + 148139 = 148378
  • 317 + 148061 = 148378

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 148,378 and was likely granted around 1873.

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