Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100398, here are decompositions:
- 5 + 100393 = 100398
- 7 + 100391 = 100398
- 19 + 100379 = 100398
- 37 + 100361 = 100398
- 41 + 100357 = 100398
- 101 + 100297 = 100398
- 107 + 100291 = 100398
- 127 + 100271 = 100398
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 100,398 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
