Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101908, here are decompositions:
- 17 + 101891 = 101908
- 29 + 101879 = 101908
- 71 + 101837 = 101908
- 101 + 101807 = 101908
- 137 + 101771 = 101908
- 167 + 101741 = 101908
- 227 + 101681 = 101908
- 281 + 101627 = 101908
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 101,908 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 101908 first appears in π at position 759,640 of the decimal expansion (the 759,640ordinal-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.
