Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 127272, here are decompositions:

  • 11 + 127261 = 127272
  • 23 + 127249 = 127272
  • 31 + 127241 = 127272
  • 53 + 127219 = 127272
  • 83 + 127189 = 127272
  • 109 + 127163 = 127272
  • 139 + 127133 = 127272
  • 149 + 127123 = 127272

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 127,272 and was likely granted around 1872.

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