Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 497820, here are decompositions:

  • 7 + 497813 = 497820
  • 19 + 497801 = 497820
  • 47 + 497773 = 497820
  • 79 + 497741 = 497820
  • 83 + 497737 = 497820
  • 101 + 497719 = 497820
  • 109 + 497711 = 497820
  • 131 + 497689 = 497820

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 497,820 and was likely granted around 1893.

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