Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100838, here are decompositions:
- 37 + 100801 = 100838
- 97 + 100741 = 100838
- 139 + 100699 = 100838
- 229 + 100609 = 100838
- 337 + 100501 = 100838
- 379 + 100459 = 100838
- 421 + 100417 = 100838
- 541 + 100297 = 100838
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 100,838 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
