Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103838, here are decompositions:

  • 37 + 103801 = 103838
  • 139 + 103699 = 103838
  • 151 + 103687 = 103838
  • 157 + 103681 = 103838
  • 181 + 103657 = 103838
  • 271 + 103567 = 103838
  • 277 + 103561 = 103838
  • 367 + 103471 = 103838

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 103 838 and was likely granted around 1870.

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