Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100038, here are decompositions:
- 19 + 100019 = 100038
- 47 + 99991 = 100038
- 67 + 99971 = 100038
- 109 + 99929 = 100038
- 131 + 99907 = 100038
- 137 + 99901 = 100038
- 157 + 99881 = 100038
- 167 + 99871 = 100038
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 100,038 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
