Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 130212, here are decompositions:

  • 11 + 130201 = 130212
  • 13 + 130199 = 130212
  • 29 + 130183 = 130212
  • 41 + 130171 = 130212
  • 113 + 130099 = 130212
  • 139 + 130073 = 130212
  • 191 + 130021 = 130212
  • 241 + 129971 = 130212

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 130,212 and was likely granted around 1872.

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