Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491576, here are decompositions:

  • 37 + 491539 = 491576
  • 73 + 491503 = 491576
  • 79 + 491497 = 491576
  • 199 + 491377 = 491576
  • 223 + 491353 = 491576
  • 277 + 491299 = 491576
  • 409 + 491167 = 491576
  • 439 + 491137 = 491576

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 491,576 and was likely granted around 1893.

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