Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 980820, here are decompositions:

  • 17 + 980803 = 980820
  • 19 + 980801 = 980820
  • 47 + 980773 = 980820
  • 89 + 980731 = 980820
  • 101 + 980719 = 980820
  • 103 + 980717 = 980820
  • 109 + 980711 = 980820
  • 131 + 980689 = 980820

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 980,820 and was likely granted around 1910.

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