Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100908, here are decompositions:
- 61 + 100847 = 100908
- 79 + 100829 = 100908
- 97 + 100811 = 100908
- 107 + 100801 = 100908
- 109 + 100799 = 100908
- 139 + 100769 = 100908
- 167 + 100741 = 100908
- 239 + 100669 = 100908
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 100,908 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 100908 first appears in π at position 138,809 of the decimal expansion (the 138,809ordinal-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.
