Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105254, here are decompositions:

  • 3 + 105251 = 105254
  • 43 + 105211 = 105254
  • 157 + 105097 = 105254
  • 223 + 105031 = 105254
  • 283 + 104971 = 105254
  • 307 + 104947 = 105254
  • 337 + 104917 = 105254
  • 547 + 104707 = 105254

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 105 254 and was likely granted around 1870.

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