Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 144758, here are decompositions:

  • 7 + 144751 = 144758
  • 181 + 144577 = 144758
  • 277 + 144481 = 144758
  • 307 + 144451 = 144758
  • 331 + 144427 = 144758
  • 349 + 144409 = 144758
  • 379 + 144379 = 144758
  • 409 + 144349 = 144758

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 144,758 and was likely granted around 1873.

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