Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100688, here are decompositions:
- 19 + 100669 = 100688
- 67 + 100621 = 100688
- 79 + 100609 = 100688
- 97 + 100591 = 100688
- 139 + 100549 = 100688
- 151 + 100537 = 100688
- 229 + 100459 = 100688
- 241 + 100447 = 100688
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 100,688 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 100688 first appears in π at position 602,843 of the decimal expansion (the 602,843ordinal-suffix:rd 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.
