Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101904, here are decompositions:

  • 13 + 101891 = 101904
  • 31 + 101873 = 101904
  • 41 + 101863 = 101904
  • 67 + 101837 = 101904
  • 71 + 101833 = 101904
  • 97 + 101807 = 101904
  • 107 + 101797 = 101904
  • 157 + 101747 = 101904

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 101,904 and was likely granted around 1870.

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