Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495438, here are decompositions:

  • 5 + 495433 = 495438
  • 17 + 495421 = 495438
  • 37 + 495401 = 495438
  • 61 + 495377 = 495438
  • 67 + 495371 = 495438
  • 79 + 495359 = 495438
  • 101 + 495337 = 495438
  • 131 + 495307 = 495438

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 495,438 and was likely granted around 1893.

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