Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990448, here are decompositions:

  • 59 + 990389 = 990448
  • 71 + 990377 = 990448
  • 89 + 990359 = 990448
  • 167 + 990281 = 990448
  • 269 + 990179 = 990448
  • 311 + 990137 = 990448
  • 449 + 989999 = 990448
  • 467 + 989981 = 990448

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 990,448 and was likely granted around 1911.

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