Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494642, here are decompositions:

  • 3 + 494639 = 494642
  • 79 + 494563 = 494642
  • 103 + 494539 = 494642
  • 199 + 494443 = 494642
  • 229 + 494413 = 494642
  • 283 + 494359 = 494642
  • 373 + 494269 = 494642
  • 541 + 494101 = 494642

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 494,642 and was likely granted around 1893.

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