Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105722, here are decompositions:

  • 31 + 105691 = 105722
  • 73 + 105649 = 105722
  • 103 + 105619 = 105722
  • 109 + 105613 = 105722
  • 181 + 105541 = 105722
  • 193 + 105529 = 105722
  • 223 + 105499 = 105722
  • 349 + 105373 = 105722

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 105,722 and was likely granted around 1870.

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