Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105930, here are decompositions:
- 17 + 105913 = 105930
- 23 + 105907 = 105930
- 31 + 105899 = 105930
- 47 + 105883 = 105930
- 59 + 105871 = 105930
- 67 + 105863 = 105930
- 101 + 105829 = 105930
- 113 + 105817 = 105930
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 105,930 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
