Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490486, here are decompositions:

  • 5 + 490481 = 490486
  • 23 + 490463 = 490486
  • 173 + 490313 = 490486
  • 239 + 490247 = 490486
  • 263 + 490223 = 490486
  • 317 + 490169 = 490486
  • 383 + 490103 = 490486
  • 389 + 490097 = 490486

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 490,486 and was likely granted around 1892.

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