Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103906, here are decompositions:
- 3 + 103903 = 103906
- 17 + 103889 = 103906
- 137 + 103769 = 103906
- 263 + 103643 = 103906
- 293 + 103613 = 103906
- 353 + 103553 = 103906
- 449 + 103457 = 103906
- 557 + 103349 = 103906
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 103,906 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
