Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501904, here are decompositions:

  • 41 + 501863 = 501904
  • 83 + 501821 = 501904
  • 101 + 501803 = 501904
  • 173 + 501731 = 501904
  • 197 + 501707 = 501904
  • 281 + 501623 = 501904
  • 311 + 501593 = 501904
  • 401 + 501503 = 501904

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 501,904 and was likely granted around 1893.

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