Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501784, here are decompositions:

  • 5 + 501779 = 501784
  • 53 + 501731 = 501784
  • 83 + 501701 = 501784
  • 167 + 501617 = 501784
  • 191 + 501593 = 501784
  • 281 + 501503 = 501784
  • 383 + 501401 = 501784
  • 401 + 501383 = 501784

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 501,784 and was likely granted around 1893.

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