Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 497840, here are decompositions:

  • 67 + 497773 = 497840
  • 103 + 497737 = 497840
  • 139 + 497701 = 497840
  • 151 + 497689 = 497840
  • 163 + 497677 = 497840
  • 181 + 497659 = 497840
  • 283 + 497557 = 497840
  • 331 + 497509 = 497840

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 497,840 and was likely granted around 1893.

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