Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100238, here are decompositions:
- 31 + 100207 = 100238
- 109 + 100129 = 100238
- 181 + 100057 = 100238
- 277 + 99961 = 100238
- 331 + 99907 = 100238
- 337 + 99901 = 100238
- 367 + 99871 = 100238
- 379 + 99859 = 100238
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 100,238 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 100238 first appears in π at position 685,910 of the decimal expansion (the 685,910ordinal-suffix:th digit after the integer 3).
Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
