Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105048, here are decompositions:
- 11 + 105037 = 105048
- 17 + 105031 = 105048
- 29 + 105019 = 105048
- 61 + 104987 = 105048
- 89 + 104959 = 105048
- 101 + 104947 = 105048
- 131 + 104917 = 105048
- 137 + 104911 = 105048
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 105 048 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
