Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100668, here are decompositions:
- 19 + 100649 = 100668
- 47 + 100621 = 100668
- 59 + 100609 = 100668
- 109 + 100559 = 100668
- 131 + 100537 = 100668
- 149 + 100519 = 100668
- 151 + 100517 = 100668
- 157 + 100511 = 100668
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 100,668 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 100668 first appears in π at position 622,027 of the decimal expansion (the 622,027ordinal-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.
