Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104040, here are decompositions:

  • 7 + 104033 = 104040
  • 19 + 104021 = 104040
  • 31 + 104009 = 104040
  • 37 + 104003 = 104040
  • 43 + 103997 = 104040
  • 47 + 103993 = 104040
  • 59 + 103981 = 104040
  • 61 + 103979 = 104040

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 104,040 and was likely granted around 1870.

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