Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105288, here are decompositions:

  • 11 + 105277 = 105288
  • 19 + 105269 = 105288
  • 37 + 105251 = 105288
  • 59 + 105229 = 105288
  • 61 + 105227 = 105288
  • 89 + 105199 = 105288
  • 151 + 105137 = 105288
  • 181 + 105107 = 105288

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 105,288 and was likely granted around 1870.

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