Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 169144, here are decompositions:

  • 47 + 169097 = 169144
  • 137 + 169007 = 169144
  • 167 + 168977 = 169144
  • 251 + 168893 = 169144
  • 257 + 168887 = 169144
  • 281 + 168863 = 169144
  • 293 + 168851 = 169144
  • 383 + 168761 = 169144

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 169,144 and was likely granted around 1874.

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