Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156836, here are decompositions:

  • 3 + 156833 = 156836
  • 13 + 156823 = 156836
  • 19 + 156817 = 156836
  • 37 + 156799 = 156836
  • 103 + 156733 = 156836
  • 109 + 156727 = 156836
  • 157 + 156679 = 156836
  • 349 + 156487 = 156836

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 156,836 and was likely granted around 1873.

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