Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105300, here are decompositions:

  • 23 + 105277 = 105300
  • 31 + 105269 = 105300
  • 37 + 105263 = 105300
  • 47 + 105253 = 105300
  • 61 + 105239 = 105300
  • 71 + 105229 = 105300
  • 73 + 105227 = 105300
  • 89 + 105211 = 105300

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 105,300 and was likely granted around 1870.

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