Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104538, here are decompositions:

  • 11 + 104527 = 104538
  • 47 + 104491 = 104538
  • 59 + 104479 = 104538
  • 67 + 104471 = 104538
  • 79 + 104459 = 104538
  • 139 + 104399 = 104538
  • 157 + 104381 = 104538
  • 191 + 104347 = 104538

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 104,538 and was likely granted around 1870.

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