Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 131582, here are decompositions:

  • 103 + 131479 = 131582
  • 151 + 131431 = 131582
  • 211 + 131371 = 131582
  • 271 + 131311 = 131582
  • 331 + 131251 = 131582
  • 379 + 131203 = 131582
  • 433 + 131149 = 131582
  • 439 + 131143 = 131582

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 131,582 and was likely granted around 1872.

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