Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509242, here are decompositions:

  • 3 + 509239 = 509242
  • 179 + 509063 = 509242
  • 269 + 508973 = 509242
  • 281 + 508961 = 509242
  • 311 + 508931 = 509242
  • 401 + 508841 = 509242
  • 431 + 508811 = 509242
  • 443 + 508799 = 509242

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 509,242 and was likely granted around 1893.

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