Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001380, here are decompositions:

  • 11 + 1001369 = 1001380
  • 53 + 1001327 = 1001380
  • 59 + 1001321 = 1001380
  • 89 + 1001291 = 1001380
  • 101 + 1001279 = 1001380
  • 113 + 1001267 = 1001380
  • 227 + 1001153 = 1001380
  • 257 + 1001123 = 1001380

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 1,001,380 and was likely granted around 1911.

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