Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145676, here are decompositions:

  • 43 + 145633 = 145676
  • 73 + 145603 = 145676
  • 127 + 145549 = 145676
  • 163 + 145513 = 145676
  • 199 + 145477 = 145676
  • 277 + 145399 = 145676
  • 373 + 145303 = 145676
  • 409 + 145267 = 145676

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 145,676 and was likely granted around 1873.

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