Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 144028, here are decompositions:

  • 29 + 143999 = 144028
  • 47 + 143981 = 144028
  • 149 + 143879 = 144028
  • 197 + 143831 = 144028
  • 317 + 143711 = 144028
  • 359 + 143669 = 144028
  • 419 + 143609 = 144028
  • 461 + 143567 = 144028

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 144,028 and was likely granted around 1873.

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