Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101272, here are decompositions:

  • 5 + 101267 = 101272
  • 89 + 101183 = 101272
  • 113 + 101159 = 101272
  • 131 + 101141 = 101272
  • 191 + 101081 = 101272
  • 251 + 101021 = 101272
  • 263 + 101009 = 101272
  • 359 + 100913 = 101272

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 101,272 and was likely granted around 1870.

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