Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101906, here are decompositions:

  • 37 + 101869 = 101906
  • 43 + 101863 = 101906
  • 67 + 101839 = 101906
  • 73 + 101833 = 101906
  • 109 + 101797 = 101906
  • 157 + 101749 = 101906
  • 307 + 101599 = 101906
  • 373 + 101533 = 101906

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 101,906 and was likely granted around 1870.

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