Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103920, here are decompositions:
- 7 + 103913 = 103920
- 17 + 103903 = 103920
- 31 + 103889 = 103920
- 53 + 103867 = 103920
- 79 + 103841 = 103920
- 83 + 103837 = 103920
- 107 + 103813 = 103920
- 109 + 103811 = 103920
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 103.920 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
