Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 168940, here are decompositions:

  • 3 + 168937 = 168940
  • 41 + 168899 = 168940
  • 47 + 168893 = 168940
  • 53 + 168887 = 168940
  • 71 + 168869 = 168940
  • 89 + 168851 = 168940
  • 137 + 168803 = 168940
  • 179 + 168761 = 168940

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 168,940 and was likely granted around 1874.

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