Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101222, here are decompositions:

  • 13 + 101209 = 101222
  • 19 + 101203 = 101222
  • 61 + 101161 = 101222
  • 73 + 101149 = 101222
  • 103 + 101119 = 101222
  • 109 + 101113 = 101222
  • 223 + 100999 = 101222
  • 241 + 100981 = 101222

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 101,222 and was likely granted around 1870.

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