Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100166, here are decompositions:
- 13 + 100153 = 100166
- 37 + 100129 = 100166
- 97 + 100069 = 100166
- 109 + 100057 = 100166
- 163 + 100003 = 100166
- 307 + 99859 = 100166
- 337 + 99829 = 100166
- 349 + 99817 = 100166
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 100,166 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 100166 first appears in π at position 292,098 of the decimal expansion (the 292,098ordinal-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.
