Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101438, here are decompositions:
- 19 + 101419 = 101438
- 61 + 101377 = 101438
- 79 + 101359 = 101438
- 97 + 101341 = 101438
- 151 + 101287 = 101438
- 157 + 101281 = 101438
- 229 + 101209 = 101438
- 241 + 101197 = 101438
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 101,438 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
