Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101660, here are decompositions:

  • 7 + 101653 = 101660
  • 19 + 101641 = 101660
  • 61 + 101599 = 101660
  • 79 + 101581 = 101660
  • 127 + 101533 = 101660
  • 157 + 101503 = 101660
  • 193 + 101467 = 101660
  • 211 + 101449 = 101660

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 101,660 and was likely granted around 1870.

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