Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143168, here are decompositions:

  • 31 + 143137 = 143168
  • 61 + 143107 = 143168
  • 199 + 142969 = 143168
  • 229 + 142939 = 143168
  • 271 + 142897 = 143168
  • 331 + 142837 = 143168
  • 379 + 142789 = 143168
  • 397 + 142771 = 143168

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 143,168 and was likely granted around 1872.

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