Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 131882, here are decompositions:

  • 43 + 131839 = 131882
  • 103 + 131779 = 131882
  • 139 + 131743 = 131882
  • 151 + 131731 = 131882
  • 181 + 131701 = 131882
  • 211 + 131671 = 131882
  • 241 + 131641 = 131882
  • 271 + 131611 = 131882

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 131,882 and was likely granted around 1872.

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