Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1004878, here are decompositions:

  • 5 + 1004873 = 1004878
  • 131 + 1004747 = 1004878
  • 191 + 1004687 = 1004878
  • 227 + 1004651 = 1004878
  • 311 + 1004567 = 1004878
  • 317 + 1004561 = 1004878
  • 401 + 1004477 = 1004878
  • 449 + 1004429 = 1004878

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 1,004,878 and was likely granted around 1911.

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