Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 500642, here are decompositions:

  • 13 + 500629 = 500642
  • 199 + 500443 = 500642
  • 211 + 500431 = 500642
  • 229 + 500413 = 500642
  • 409 + 500233 = 500642
  • 433 + 500209 = 500642
  • 463 + 500179 = 500642
  • 523 + 500119 = 500642

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 500,642 and was likely granted around 1893.

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