Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100488, here are decompositions:
- 5 + 100483 = 100488
- 19 + 100469 = 100488
- 29 + 100459 = 100488
- 41 + 100447 = 100488
- 71 + 100417 = 100488
- 97 + 100391 = 100488
- 109 + 100379 = 100488
- 127 + 100361 = 100488
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 100,488 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
