Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 157744, here are decompositions:

  • 5 + 157739 = 157744
  • 11 + 157733 = 157744
  • 23 + 157721 = 157744
  • 107 + 157637 = 157744
  • 173 + 157571 = 157744
  • 311 + 157433 = 157744
  • 317 + 157427 = 157744
  • 467 + 157277 = 157744

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 157,744 and was likely granted around 1873.

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