Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145316, here are decompositions:

  • 13 + 145303 = 145316
  • 97 + 145219 = 145316
  • 103 + 145213 = 145316
  • 109 + 145207 = 145316
  • 139 + 145177 = 145316
  • 307 + 145009 = 145316
  • 349 + 144967 = 145316
  • 433 + 144883 = 145316

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 145,316 and was likely granted around 1873.

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