Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001258, here are decompositions:

  • 61 + 1001197 = 1001258
  • 67 + 1001191 = 1001258
  • 151 + 1001107 = 1001258
  • 241 + 1001017 = 1001258
  • 277 + 1000981 = 1001258
  • 337 + 1000921 = 1001258
  • 397 + 1000861 = 1001258
  • 409 + 1000849 = 1001258

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 1,001,258 and was likely granted around 1911.

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