Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105488, here are decompositions:
- 109 + 105379 = 105488
- 127 + 105361 = 105488
- 151 + 105337 = 105488
- 157 + 105331 = 105488
- 211 + 105277 = 105488
- 277 + 105211 = 105488
- 457 + 105031 = 105488
- 541 + 104947 = 105488
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 105,488 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
