Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178474, here are decompositions:

  • 5 + 178469 = 178474
  • 71 + 178403 = 178474
  • 113 + 178361 = 178474
  • 167 + 178307 = 178474
  • 173 + 178301 = 178474
  • 227 + 178247 = 178474
  • 251 + 178223 = 178474
  • 347 + 178127 = 178474

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 178,474 and was likely granted around 1875.

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