Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100158, here are decompositions:
- 5 + 100153 = 100158
- 7 + 100151 = 100158
- 29 + 100129 = 100158
- 89 + 100069 = 100158
- 101 + 100057 = 100158
- 109 + 100049 = 100158
- 139 + 100019 = 100158
- 167 + 99991 = 100158
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 100,158 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 100158 first appears in π at position 16,905 of the decimal expansion (the 16,905ordinal-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.
