Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145214, here are decompositions:

  • 7 + 145207 = 145214
  • 37 + 145177 = 145214
  • 151 + 145063 = 145214
  • 193 + 145021 = 145214
  • 241 + 144973 = 145214
  • 283 + 144931 = 145214
  • 331 + 144883 = 145214
  • 367 + 144847 = 145214

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 145,214 and was likely granted around 1873.

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