Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104878, here are decompositions:

  • 29 + 104849 = 104878
  • 47 + 104831 = 104878
  • 89 + 104789 = 104878
  • 149 + 104729 = 104878
  • 167 + 104711 = 104878
  • 197 + 104681 = 104878
  • 227 + 104651 = 104878
  • 239 + 104639 = 104878

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 104,878 and was likely granted around 1870.

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