Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104280, here are decompositions:

  • 37 + 104243 = 104280
  • 41 + 104239 = 104280
  • 47 + 104233 = 104280
  • 73 + 104207 = 104280
  • 97 + 104183 = 104280
  • 101 + 104179 = 104280
  • 107 + 104173 = 104280
  • 131 + 104149 = 104280

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 104,280 and was likely granted around 1870.

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