Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490448, here are decompositions:

  • 31 + 490417 = 490448
  • 109 + 490339 = 490448
  • 139 + 490309 = 490448
  • 181 + 490267 = 490448
  • 199 + 490249 = 490448
  • 241 + 490207 = 490448
  • 331 + 490117 = 490448
  • 337 + 490111 = 490448

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 490,448 and was likely granted around 1892.

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