Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 130968, here are decompositions:

  • 11 + 130957 = 130968
  • 41 + 130927 = 130968
  • 109 + 130859 = 130968
  • 127 + 130841 = 130968
  • 139 + 130829 = 130968
  • 151 + 130817 = 130968
  • 157 + 130811 = 130968
  • 181 + 130787 = 130968

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 130,968 and was likely granted around 1872.

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