Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491300, here are decompositions:

  • 3 + 491297 = 491300
  • 151 + 491149 = 491300
  • 163 + 491137 = 491300
  • 241 + 491059 = 491300
  • 307 + 490993 = 491300
  • 331 + 490969 = 491300
  • 349 + 490951 = 491300
  • 373 + 490927 = 491300

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 491,300 and was likely granted around 1892.

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