Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104940, here are decompositions:

  • 7 + 104933 = 104940
  • 23 + 104917 = 104940
  • 29 + 104911 = 104940
  • 61 + 104879 = 104940
  • 71 + 104869 = 104940
  • 89 + 104851 = 104940
  • 109 + 104831 = 104940
  • 113 + 104827 = 104940

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 104,940 and was likely granted around 1870.

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