Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105220, here are decompositions:

  • 47 + 105173 = 105220
  • 53 + 105167 = 105220
  • 83 + 105137 = 105220
  • 113 + 105107 = 105220
  • 149 + 105071 = 105220
  • 197 + 105023 = 105220
  • 233 + 104987 = 105220
  • 389 + 104831 = 105220

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 105.220 and was likely granted around 1870.

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