Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104640, here are decompositions:

  • 17 + 104623 = 104640
  • 43 + 104597 = 104640
  • 47 + 104593 = 104640
  • 61 + 104579 = 104640
  • 79 + 104561 = 104640
  • 89 + 104551 = 104640
  • 97 + 104543 = 104640
  • 103 + 104537 = 104640

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 104.640 and was likely granted around 1870.

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