Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104920, here are decompositions:
- 3 + 104917 = 104920
- 29 + 104891 = 104920
- 41 + 104879 = 104920
- 71 + 104849 = 104920
- 89 + 104831 = 104920
- 131 + 104789 = 104920
- 191 + 104729 = 104920
- 197 + 104723 = 104920
Showing the first eight; more decompositions exist.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 104,920 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
