Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 144470, here are decompositions:

  • 19 + 144451 = 144470
  • 31 + 144439 = 144470
  • 43 + 144427 = 144470
  • 61 + 144409 = 144470
  • 163 + 144307 = 144470
  • 181 + 144289 = 144470
  • 199 + 144271 = 144470
  • 211 + 144259 = 144470

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 144,470 and was likely granted around 1873.

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