Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101830, here are decompositions:

  • 23 + 101807 = 101830
  • 41 + 101789 = 101830
  • 59 + 101771 = 101830
  • 83 + 101747 = 101830
  • 89 + 101741 = 101830
  • 107 + 101723 = 101830
  • 137 + 101693 = 101830
  • 149 + 101681 = 101830

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 101,830 and was likely granted around 1870.

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