Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101138, here are decompositions:
- 19 + 101119 = 101138
- 31 + 101107 = 101138
- 139 + 100999 = 101138
- 151 + 100987 = 101138
- 157 + 100981 = 101138
- 181 + 100957 = 101138
- 211 + 100927 = 101138
- 337 + 100801 = 101138
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 101,138 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
