Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103870, here are decompositions:

  • 3 + 103867 = 103870
  • 29 + 103841 = 103870
  • 59 + 103811 = 103870
  • 83 + 103787 = 103870
  • 101 + 103769 = 103870
  • 167 + 103703 = 103870
  • 227 + 103643 = 103870
  • 251 + 103619 = 103870

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 103.870 and was likely granted around 1870.

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